Hettich HSS 31 EN 1-3 Surface Mounted Door Closer with Slide Rail
Overview
The Hettich HSS 31 EN 1-3 is a surface-mounted door closer with slide rail (Slide Rail B) designed for fixed back-check performance. It uses a rack and pinion (asymmetric) mechanism, is EN1154-certified, fire-rated, and tested through 500,000 open/close cycles. It is built for doors weighing 20-80 Kg with a width of 750-950 mm.
What It Does
This door closer automatically and smoothly closes doors after they are opened, using a rack-and-pinion mechanism with adjustable closing and latching speeds. The slide rail design (as opposed to a linkage arm) gives a low-profile, fixed back-check function that limits how far the door can swing open, protecting the door and closer from damage.
