Abstract

A door closer comprises an elongate housing 2 for mounting in one of the door leaf or door frame, a plunger 6 disposed in and movable along the housing, a biasing element 4 disposed in the housing and biasing the plunger inwardly of the housing, and a tension member 14 having a first end pivotally connected at a first pivot 18 to the plunger and a second end, an anchor element assembly to which the second end is pivotally connected at a second pivot. A hydraulic damper for damping the movement of the plunger within the housing is provided, the hydraulic damper including a threaded adjuster pin 52 for adjusting the operation of the hydraulic damper, the threaded adjuster pin being captive in the plunger 6 by the first pivot 18.
