Abstract

This is a saddle (8), with a circular cavity supporting surface, which corresponds to the diameter of an unloaded balancing spring (3) for a sectional door, with a development less than 180° to allow fitting the saddle (8) to the spring (3) it must support.
The saddle (8) is fitted beneath the spring (3) and supported by a bracket (5) fixed to the crosspiece (1) of the fixed frame of the sectional door. The saddle (8) clicks and releases from the bracket (5).
