These roller-equipped windlocks are designed for rolling steel door systems that may operate under wind load.
When wind pressure pushes the door curtain against the guide during operation, the integrated rollers help the windlocks move smoothly through the guide slot. This reduces dragging and binding as the curtain travels.
The roller design helps support smoother door operation in windy conditions. It also helps reduce wear on the windlocks, guides, and rolling door curtain.
These parts are used with compatible rolling steel door curtain and guide assemblies that require roller-equipped windlocks.
Package Note*: Sold as a 20-piece pack. Price shown is per pack.
