Hager ECBB1100 NRP 4-1/2" x 4-1/2" Ball Bearing Hinge
The Hager ECBB1100 NRP is a premier choice for full mortise [link] applications on medium-weight doors. Engineered for longevity and security, this steel ball bearing hinge features a plated finish that provides both a professional aesthetic and corrosion resistance. It is specifically designed for 1-3/4" thick doors that require low-frequency service but high-security standards.
Enhanced Security with Non-Removable Pin (NRP)
The standout feature of this hinge is the NRP (Non-Removable Pin). On standard hinges, the pin can be tapped out from the outside, allowing the door to be removed even if it is locked. The Hager NRP uses a set screw in the barrel that is only accessible when the door is open. This makes it an essential security component for outward swinging doors, effectively preventing unauthorized entry and hinge manipulation.
Smooth Operation and Durability
Built with two ball bearings, the ECBB1100 reduces friction and prevents sagging over time. This ensures a smooth, quiet swing for your door assembly. Compliant with ANSI A8112 standards, this hinge is a reliable solution for both residential and commercial projects where peace of mind and structural integrity are non-negotiable.
