Zipbolt Angled Railbolt Bundle for Handrail to Newel Post – 11.560 Lower + 13.960 Upper Connectors

Overview

Meet the Zipbolt UT Angled Railbolt Bundle, a purpose-built solution for attaching angled handrails to newel posts with a hidden fastener. This kit combines two components—the 11.560 lower connector and the 13.960 upper connector—designed to work together for a seamless, durable joint. The patented gear-driven UT mechanism lets you tighten from within the handrail at a right angle, while a pivoting 8mm shaft threads securely into the post with a wood-thread coach bolt. The result is a robust connection that stays flush without long screws through the face of the post or messy filled nail holes.

What makes this bundle practical is how it adapts to real stair layouts. The pivoting shaft allows the angle to open or close as needed, so you get a precise fit on angled staircases, including upper joints. The kit’s housing design avoids bulky nuts and washers, simplifying installation and reducing visible hardware. Built for both residential and commercial environments, it promises repeatable strength under daily use, with a clean aesthetic that complements modern stair designs.

What’s included and how it’s used

• Two connectors for angled handrail installations: 11.560 lower and 13.960 upper.
• Two angled slipfix rail bolts for secure upper connections.
• Two Torx drivers (T30) and four red oak plugs for on-site assembly.
• Clear packaging instructions to guide the two-rail installation process.

• Lower connection: insert the railbolt into a reamed post, apply light wax to ease insertion, align the gear housing in the handrail, and tighten with the Torx driver until snug.
• Upper connection: assemble the shaft and gear housing inside the rail, slot the keyhole disc, then tighten to create a firm joint.

The design emphasizes a smooth, concealed finish, and the gear-driven action is intended to provide consistent clamping force without overt hardware on the surface. Note that impact drivers are not recommended for tightening the gear housing, in line with the installation guidance.

Durability and value

Crafted from quality steel, the Zipbolt bundle is built for long-term reliability in busy stair settings. Professionals appreciate the fast, accurate alignment and the ability to recreate strong joints across multiple projects with a repeatable method.
