RHR            30846
LHR            30847

The CRL Jackson 1095 Series Back Plate Sub-Assembly is a critical structural component engineered for the mounting and mechanical operation of Jackson 1095 Rim Panic Exit Devices. This heavy-duty sub-assembly serves as the internal foundation that anchors the exit device chassis to the door stile, ensuring that the push bar or crossbar remains perfectly aligned under constant use. Designed to accommodate 1-3/4" (44.5 mm) doors, this part is the primary hardware solution for retrofitting or repairing exit hardware on narrow, medium, or wide stile aluminum, wood, or hollow metal doors.

Available in specific handings—30846 for Right Hand Reverse (RHR) and 30847 for Left Hand Reverse (LHR)—this sub-assembly is a high-performance maintenance solution for high-traffic commercial entrances. Whether you are addressing a "sagging" panic bar or replacing a damaged mounting plate during a facility upgrade, this genuine Jackson OEM part restores the structural integrity of the door opening. By providing a rigid mounting surface, it eliminates the mechanical "slop" that leads to latching failures, ensuring your facility remains compliant with building safety codes and storefront security standards.

Exit Device Mechanical Function & ANSI Summary

The Back Plate Sub-Assembly is the mechanical "spine" of the rim exit device, playing a vital role in the translation of force from the push bar to the latch bolt.

• Chassis Stabilization: This assembly prevents the exit device from shifting during operation, which is the leading cause of internal component wear and misalignment.
• Force Distribution: It distributes the physical pressure of emergency egress across the door stile, preventing the "crushing" or warping of thin-walled aluminum stiles.
• ANSI/BHMA Compliance: When used with a complete Jackson 10 Series device, this assembly supports ANSI/BHMA A156.3, Grade 1 standards, the highest rating for durability and security in the hardware industry.
• Handed Precision: Because rim devices are handed, the 30846 and 30847 assemblies feature factory-set pivot points and spring tensions specifically calibrated for RHR or LHR configurations, ensuring smooth, predictable latch retraction.

Technical Specifications

Engineered Solutions for Commercial Openings

The CRL Jackson 30846 and 30847 sub-assemblies provide targeted solutions for facility managers and glazing contractors:

• Eliminate Latch Binding: If your exit device is sticking or failing to latch, the culprit is often a warped or loose back plate. This sub-assembly is the permanent solution for restoring the flush alignment required for a secure, "first-time" latching action.
• Universal Door Versatility: While optimized for aluminum storefronts, the mounting footprint is a reliable retrofit solution for wood or hollow metal doors that require the durability of a Jackson 1095 rim device.
• Enhanced Storefront Security: A loose panic bar is a vulnerability. Replacing a worn back plate ensures the device cannot be easily manipulated or pried from the exterior, maintaining a secure perimeter solution.
• Simplified Field Repair: Instead of replacing the entire exit device, which can cost hundreds in parts and labor, the Back Plate Sub-Assembly allows for a targeted component-level repair, significantly reducing maintenance overhead.
• Operational Longevity: By absorbing the mechanical stress of thousands of daily cycles, this heavy-duty sub-assembly protects the more delicate internal springs and cams of the panic bar, acting as a life-cycle extension solution for your door hardware.
