Description

Built for high‑traffic openings, this concealed bottom pivot with integrated floor spring uses a hardened‑steel body and a precise cam mechanism to deliver quiet, secure closing. A defined latch feel and a 90° hold position enable hands‑free operation when needed. Dual valves let you fine‑tune the closing speed in the 70°→25° and 25°→0° ranges, while the 85°→70° segment is fixed for consistent motion. The 2D adjustable floor plate (radial + axial) simplifies on‑site leveling and centering. Designed for double‑acting wooden or metal doors with minimum 40 mm thickness and side‑placement pivot geometry; supports door widths up to 1100 mm and weights up to 120 kg. Tested to 500,000 cycles, with EN3/EN4/EN5 closing force options and an optional adjustable top pivot and ceiling plate.
