Equip commercial doors with smooth operation, durability, and added hinge-side security using the Vector Hinge Co. 4-1/2" x 4" Ball Bearing NRP Hinge.

Designed for commercial and institutional openings, this hinge features ball-bearing construction to reduce friction and wear during frequent operation. The Non-Removable Pin (NRP) helps prevent hinge-pin removal when the door is closed, making it especially useful for secure and outswinging openings.

The 1/4" radius corners are designed for doors and frames prepared for rounded-corner hinges.

Choose from US32D Satin Stainless Steel, US26D Satin Chrome, or US10B Oil-Rubbed Bronze.

• 1/4" radius corner preparation

• Door and frame hinge locations

• Door thickness
