Concrete light poles have a recessed hand hole cover that provides access to the internal wiring. Unlike standard pole covers, these bolt directly into the pole body — but the factory cover still offers no real security. Any thief with a wrench can remove one in under a minute and walk off with the copper wire inside.
The EMT Curved 2-Bolt Hand Hole Lock is designed specifically for curved and round-body concrete light poles with recessed hand hole openings. The contoured back plate seats flush against the pole’s curve, bolt 1 secures it to the pole, the top cover plate snaps over and conceals bolt 1 completely, and bolt 2 locks the top plate in place behind an integrated puck lock — no exposed hardware, nothing to grip or cut.

Why Copper Thieves Target Curved Concrete Light Poles
Curved concrete poles present a specific problem — a flat cover won’t seat flush against a round pole body. As a result, these poles often carry worn, ill-fitting factory covers that any thief with a wrench can remove in seconds. A single theft incident can run $1,000–$2,000+ to repair. One lock stops that.
How It Works
The curved 2-bolt hand hole lock is a two-piece steel retrofit cover designed for curved and round-body concrete poles where bolts thread directly into the pole — no bracket required.
The contoured back plate seats flush against the pole’s curve and is secured with bolt 1. The top cover plate snaps over, completely concealing bolt 1. Bolt 2 then locks the top plate in place behind an integrated puck lock — both bolts fully hidden, no exposed hardware, nothing to grip or cut.

How to Measure for the Curved 2-Bolt System
This system is different from the single-bolt bracket cover. The back plate sits into the recessed opening and bolts directly into the pole — so fit depends on four things: the opening size, the bolt spacing, the bolt specs, and the pole circumference. Here’s what to measure:
Measure the width and height of the recessed opening in the pole — this is where the back plate sits. Measure the full recess, not just the inner void.

Opening Width

Opening Height
Measure the center-to-center distance between the two bolt holes in the pole. Also measure the distance from the edge of the opening to each bolt hole — both horizontally and vertically. These measurements determine where the bolt holes are drilled on your custom cover plate.
Note the bolt diameter, length, and thread count from your existing hardware. The bolts thread directly into the pole’s existing threaded inserts — they must match exactly. If you’re unsure, send your existing cover with hardware and we’ll identify the specs.
Wrap a flexible tape measure around the pole at the hand hole location and record the full circumference. EMT uses this to contour the back plate to your pole’s exact radius — the top plate then fits flush over the back plate.

Important: Both pole circumference and bolt placement are critical for this system. The back plate must seat flush against the pole curve, and the bolt holes must align precisely with your pole’s threaded inserts. Sending your existing cover with hardware to 1745 W Deer Valley Rd, Suite 110, Phoenix, AZ 85027 is the most reliable way to get a correct fit — especially for custom orders. EMT cannot correct curvature or bolt placement after fabrication.

Custom curved 2-bolt covers are fabricated to your exact opening dimensions, bolt pattern, and pole circumference — with the same puck-lock security and powder-coated steel. Lead time is typically 6–8 weeks. Sending your existing cover with hardware is strongly recommended. Request a custom size →
What is a curved 2 bolt hand hole lock, and how does it differ from the flat version?
The flat 2-bolt hand hole lock uses a flat back plate that seats into a recessed opening on a flat-body concrete pole. The curved 2-bolt system, however, uses a contoured back plate profile that matches the curve of a round or curved-body pole. Both systems use the same two-piece design and puck lock security. The key difference is the back plate profile — flat for flat poles, contoured for curved poles.
How do I know if the curved 2 bolt hand hole lock is the right product for my pole?
If your pole has a curved or round body at the hand hole location and the bolts thread directly into the pole rather than into a bracket, the curved 2-bolt system is likely the correct fit. If you are unsure, contact us at 480.745.3999 or info@endmetaltheft.com. We’ll help you identify the right product or initiate a custom order.
How do I measure my pole circumference for a curved 2 bolt hand hole lock?
Wrap a flexible tape measure around the pole at the hand hole location and record the full circumference. EMT uses this measurement to match the back plate’s contour to your pole body. If you are unsure, sending your existing cover with hardware is the most reliable way to ensure a correct fit.
Can I order this if I don’t have my pole measurements?
Yes — but a custom order will be required. Send your existing cover with hardware to 1745 W Deer Valley Rd, Suite 110, Phoenix, AZ 85027. We’ll take all required measurements and fabricate a cover to fit. Alternatively, provide the measurements listed in the sizing section above and we’ll confirm fit before fabrication begins.
How difficult is installation?
Installation is straightforward and typically takes under 15 minutes. First, secure the contoured back plate to the pole with bolt 1. Next, snap the top cover plate over the back plate, concealing bolt 1. Then thread bolt 2 into the pole through the top cover plate and tighten. Finally, drop the puck lock over bolt 2 and lock it in place. Full instructions ship with every order.
Can I key multiple curved 2 bolt hand hole locks to the same key?
Yes — keyed alike options are available. A single key works across multiple locks on the same property or across an entire fleet of poles. Simply contact EMT when ordering to request keyed alike configuration.
What if a thief tries to cut the lock?
The puck lock sits inside a shrouded steel body that blocks access to the shackle by bolt cutters. Additionally, both bolts are fully concealed — bolt 1 sits behind the top cover plate, and bolt 2 sits behind the puck lock housing. While no lock offers absolute protection, the goal is to make your poles a harder target than unprotected alternatives nearby. Consequently, thieves move on.
How long will the curved 2 bolt hand hole lock last outdoors?
Heavy-gauge steel construction with a powder-coated finish effectively resists rust, corrosion, and UV exposure. Furthermore, every unit carries a Limited Lifetime Warranty against manufacturing defects. For best long-term performance, we recommend annual inspection as part of routine pole maintenance.
What is the lead time for the stock SKU?
The stock SKU ships within 1 business day from our Phoenix, AZ facility. Custom orders, however, require approximately 6–8 weeks from the time of order confirmation.

Not the Right Fit?
If your pole has a flat body at the hand hole location and the bolts thread directly into the pole, you need the Flat 2-Bolt Hand Hole Lock instead. If your pole uses an internal bracket system rather than bolts threaded into the pole, see the Flat Hand Hole Lock Standard or Flat Hand Hole Lock Heavy Duty. Not sure which product fits your pole? Call us at 480.745.3999 or request a quote and we’ll point you to the right solution.
The curved 2-bolt flat hand hole lock installs in minutes using tools you already have on the truck. No drilling, no welding, no specialty equipment required.
What’s Included
- Contoured steel back plate (powder-coated dark bronze)
- Steel top cover plate (powder-coated dark bronze)
- Two stainless-steel bolts
- Integrated EMT puck lock with 2 keys
Tools Required
- Socket wrench or adjustable wrench
- Puck lock key (included)
Installation Steps
- Remove the existing cover. Unscrew and remove your current hand hole cover and hardware from the pole.
- Position the contoured back plate. Place the back plate over the hand hole opening, aligning the bolt holes on the plate with the threaded inserts in the pole. The contoured profile of the back plate should sit flush against the curved pole body.
- Secure the back plate. Insert bolt 1 through the back plate and thread it into the pole. Tighten with a socket or adjustable wrench until the back plate sits firm and flush against the pole body.
- Snap on the top cover plate. Place the top cover plate over the back plate. The top plate snaps into position, concealing bolt 1 completely.
- Secure the top cover plate. Insert bolt 2 through the top cover plate and thread it into the pole. Tighten with a socket or adjustable wrench until the top plate sits firm and flush against the back plate.
- Engage the puck lock. Drop the puck lock over bolt 2 and lock it in place with the included key. Bolt 2 is now fully concealed with no exposed hardware.
Important Notes Before Installing
- Confirm curvature match before installing. The contoured back plate must sit flush against your pole body. If the back plate rocks or gaps against the pole surface, stop installation and contact us at 480.745.3999 before proceeding. A gap between the back plate and pole body indicates a curvature mismatch.
- Confirm bolt alignment before installing. The bolt holes on the cover plate must align precisely with the threaded inserts in your pole. If the bolt holes do not align, do not force the installation — contact us at 480.745.3999 before proceeding.
- Concrete and aggregate poles only. This product threads directly into the pole. It does not use an internal backing bracket. If your pole requires a bracket-based system, order the Flat Hand Hole Lock Standard instead.
- Tighten both bolts evenly. Tighten bolt 1 and bolt 2 to equal tension. Uneven tightening can cause the cover plate to sit off-center or create gaps around the edges.
- Keyed alike installs. If you ordered keyed alike locks for a multi-pole deployment, verify all locks share the same key code before installing across your site.
- Do not overtighten. Tighten each bolt until the cover sits firm and flush. Overtightening can strip the threaded inserts in the pole.
