Curved Hand Hole Lock - 2 Bolt System

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.

• Two-Piece System - Both Bolts Fully Concealed
  The back plate and top cover plate work together to completely hide both bolts. No exposed hardware, nothing to grip or cut.
• Contoured for Curved and Round-Body Concrete Poles
  The back plate follows your pole’s radius and seats flush - no gaps, no rocking, no pry points.
• Bolts Into the Pole - No Bracket Required
  Threads directly into the pole’s existing inserts. Built for recessed hand holes on concrete poles where bracket-based covers won’t work.
• Puck Lock Included - Shrouded Steel Housing
  Blocks bolt cutter access to the shackle. Once locked, there’s no accessible entry point for thieves.
• Heavy-Gauge Steel, Lifetime Warranty
  Powder-coated for rust, corrosion, and UV resistance. Backed by a Limited Lifetime Warranty against manufacturing defects.
• Installs in Minutes
  No drilling, no welding, standard hand tools. Full instructions included.

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.

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.

• Electrical Contractors - Purpose-built for concrete poles where bracket-based covers won’t work.
• Property & Facility Managers - Protect curved-pole perimeter lighting across single- or multi-site portfolios.

• Electrical Distributors - A purpose-built SKU for customers with curved or round-body concrete pole inventory.

The curved 2-bolt flat hand hole lock serves curved and round-body concrete light poles where the hand hole opening is recessed into the pole body and the bolts thread directly into the pole rather than into a bracket. If your pole has a curved body at the hand hole location, this is the right product. Below are the most common pole types and environments where this lock delivers results.

• Curved and round-body concrete poles - Stock SKU CHL3-1/2X10R fits poles with a 3-1/2″ × 10″ recessed opening. Confirm pole circumference before ordering.
• Aggregate and spun concrete poles - Round-body spun concrete poles with recessed hand hole openings and threaded inserts are a direct application for this product.
• Other curved concrete poles - Custom fabrication available for any curved pole not matched by the stock SKU. Sending the existing cover with hardware is strongly recommended.

• Streetlights and roadway lighting on round-body concrete poles
• Parking lot and area lighting on curved aggregate poles
• Sports field and athletic facility lighting standards
• Campus, university, and healthcare facility exterior lighting

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?
