Key benefits Provides a reliable way to fasten a dovetail plate that lacks an upper threaded hole without modifying the plate. Protects the dovetail plate from damage by using a cushion block to distribute pressure and align the screw rod. Uses existing screw holes on the guide ring for a secure, lowprofile connection that is easy to assemble and disassemble. What it does and why you need it Solves the common problem of unthreaded dovetail plates by routing the screw rod under the plate and fastening into the guide ring, eliminating the need to tap threads. Keeps assemblies aligned and secure while reducing risk of strip ping or deformation that can occur when forcing threads into thin or delicate plates. Quick field or retrofit solution for components that must remain functional without permanent modification. How to install (concise steps) 1. Confirm the upper hole of the dovetail plate is unthreaded. 2. Place the cushion block under the dovetail plate so it sits between the plate and the screw rod. The cushion block protects the plate and centers the screw rod. 3. Pass the screw rod upward through the cushion block and through the unthreaded hole in the dovetail plate. 4. Align the screw rod with the screw holes on the guide ring. 5. Screw the rod into the guide ring's threaded hole(s) until the assembly is secure. Compatibility and function Intended for dovetail plates that do not have threads in their upper hole and for guide rings that provide screw holes for fastening. Works with standard screw rods that match the guide ring's threaded holes. Function: provides mechanical fastening and alignment between the dovetail plate and the guide ring using a cushion block to protect and stabilize the plate. Performance and durability Delivers a stable connection by anchoring into the guide ring's threaded holes rather than relying on threads in thin plate material. Cushion block reduces point loading and helps maintain the integrity of the dovetail plate during repeated assembly/disassembly. Typical use scenarios Retrofitting an older dovetailmounted accessory that lacks tapped holes so it can be mounted to a guide ring without drilling or tapping. Field or temporary assembly when a dovetail plate has been stripped or cannot accept threads. Situations that require gentle clamping pressure on a delicate plate—use the cushion block to prevent deformation while still achieving a secure mount. Notes and practices Verify the screw rod diameter and thread size match the guide ring's threaded holes before assembly. Use an appropriately sized cushion block to ensure even pressure distribution and proper alignment. Do not overtighten; tighten until secure to avoid stress on the dovetail plate or guide ring threads.
