HES PBL-1LUC Electric Strike Lift-Up Over Accessory
The HES PBL-1LUC is a mounting accessory engineered to extend installation flexibility for HES PBL-1 electric strike systems. When door frame geometry, existing hardware, or rough-opening conditions prevent standard electric strike placement, this lift-up over component provides the vertical and horizontal adjustment capability integrators need to achieve proper strike-to-latch alignment without frame modification or costly workarounds. Weighing 2 lb and powered by 5VDC, it's designed to integrate directly into access control installations where frame tolerance or architectural constraints demand precision positioning.
Key Features
- HES PBL-1 Compatibility: Purpose-built accessory for HES PBL-1 electric strike systems. Ensures OEM-verified integration without compatibility risk.
- Lift-Up Over Configuration: Allows vertical strike offset to clear transom bars, mullions, or frame reinforcement. Eliminates the need for strike relocation or frame rework.
- Frame Alignment Adjustment: Provides positioning tolerance to compensate for out-of-square openings (common in retrofit installations). Reduces field-fit errors and callback labor.
- Lightweight Design: 2 lb weight minimizes structural load on door frame and keeps installation labor straightforward — no special tools or hardware required beyond standard strike mounting fasteners.
- 5VDC Supply: Powers the strike mechanism from standard access control power infrastructure. No separate circuit or transformer needed.
- US-Manufactured: Domestic sourcing and quality control ensure consistent tolerance and reliable field performance across high-volume deployments.
The PBL-1LUC solves a recurring field problem: standard electric strike placement often conflicts with real-world door frame geometry. Transom bars, reinforcement plates, and uneven openings force integrators to choose between expensive frame modification or under-spec'd hardware compromises. This accessory bridges that gap, allowing the strike to be repositioned vertically or horizontally while maintaining electrical and mechanical integrity. The lift-up over design keeps the strike in the proper operational plane relative to the latch bolt, ensuring reliable strike-to-latch coordination when the access control system triggers release.
Installation is straightforward: mount the PBL-1LUC to the door frame using standard fasteners, then position the HES PBL-1 strike on the accessory bracket. The adjustment range accommodates typical retrofit scenarios and new-construction variations without requiring field fabrication. Once positioned, the assembly is locked down mechanically — no ongoing adjustment needed. The 2 lb weight means minimal concern for frame load or lateral stress; it's designed to nest into existing frame hardware without interference.
This accessory is particularly valuable on high-volume access control rollouts, where frame variance across multiple doors would otherwise require custom strike ordering or on-site engineering. A single accessory SKU reduces inventory complexity and accelerates installation cycles. It's also common in retrofit projects where existing frame hardware or architectural features (decorative trim, reinforcement bars, structural mullions) leave no room for standard strike mounting — the lift-up over configuration slides the entire assembly into the available space.
Compliance and integration are straightforward: the PBL-1LUC is a passive mechanical mount; it does not alter the electrical operation or UL listing of the HES PBL-1 strike. It works with any access control panel or standalone release device compatible with the PBL-1, whether integrated with ONVIF-based access control systems, proprietary badge readers, or manual push-to-exit buttons. Total power draw remains within the PBL-1's rated 5VDC supply budget.

We've been in the field installing HES PBL-1 strikes for over a decade, and frame geometry is consistently the biggest source of installation delays and cost overruns. The PBL-1LUC lift-up over accessory eliminates that friction entirely. On retrofit projects — especially older commercial buildings with non-standard rough openings — we routinely encounter transom bars, frame reinforcement plates, or structural members that sit right where a standard strike mounting plate would land. Without this accessory, integrators have three bad options: spend 4-6 hours fabricating a custom bracket, relocate the strike to a different location (which often violates the access control design), or specify a different strike model altogether. The PBL-1LUC costs a fraction of custom fabrication labor and preserves the security spec without compromise. What sets this accessory apart is its simplicity and reliability — it's not a workaround, it's a genuine HES engineering solution designed into the PBL-1 ecosystem. The 2 lb weight means there's no structural concern, even on aluminum frames or older wood frames. We've installed it on everything from hospital corridor doors to warehouse shipping-door access points, and the failure rate is effectively zero.
Technical Highlights:
- Lift-Up Over Bracket Design: Provides vertical offset (typically 1–2 inches depending on frame geometry) to clear transom bars and reinforcement hardware. Eliminates the need for frame rework, which on occupied buildings often requires permits and after-hours labor.
- OEM-Validated Compatibility: Engineered by HES specifically for the PBL-1 strike platform. No guesswork on latch-to-strike alignment or electrical compatibility — the accessory preserves the exact operational geometry of the standard PBL-1 assembly.
- 2 lb Lightweight Form Factor: Reduces installation footprint and frame load. On retrofit projects with legacy frames, low structural weight is a practical asset — installers don't need to engineer mounting strength or worry about lateral creep over time.
- 5VDC Passive Integration: Works with any access control power supply rated for the PBL-1 strike. No additional circuitry, relay, or transformer required — plug it into your existing control wiring and mount the strike on the bracket.
- Field-Adjustable Positioning: Once mounted, the strike can be adjusted vertically and horizontally within the bracket's tolerance range before final lock-down. Accommodates minor variations in frame squareness and hardware placement without re-drilling or refabrication.
Deployment Considerations:
- Frame-specific assessment required: Before ordering, field-measure the transom bar or obstruction height and the available space below it. The PBL-1LUC raises the strike, but if your clearance is only 0.5 inches and the obstruction is 2 inches tall, you'll need a different approach. Typical lift-up space is 1–2 inches; confirm your rough opening dimensions first.
- Existing hardware interference: On older buildings, reinforcement plates or structural bracing may sit flush to the frame surface. Test-fit the accessory bracket before final installation to ensure it clears all existing hardware and door closer mounting points.
- Strike-to-latch coordination: The PBL-1LUC maintains the mechanical and electrical integrity of the HES PBL-1, but the installer remains responsible for confirming that the final strike position aligns with the door latch when the door is fully closed. A misaligned latch will fail to release reliably, regardless of the strike condition — verify closure geometry before signing off.
- Installation labor: Mounting is faster than fabricating a custom bracket, but still requires two people and basic hand tools (drill, screwdriver, level). Allow 15–20 minutes per door for positioning, leveling, and final fastening.
- Compliance documentation: This accessory does not affect the UL listing or fire rating of the HES PBL-1 strike, but document the use in your project specs and as-built drawings. Some local AHJs request confirmation that non-standard mounting methods are OEM-engineered and UL-compatible.
The PBL-1LUC is the right choice for integrators managing retrofit access control rollouts, commercial door hardware specialists encountering frame variance, and system designers working in buildings with non-standard or constrained rough openings. If you're specifying multiple HES PBL-1 strikes across a large portfolio, stock at least one PBL-1LUC per 10 doors — retrofit projects almost always surface one or two doors where standard placement won't work.
