## Installation

- Details
In the closed position place the flanges of both lower brackets on the base of the seat box. Fix them with wood screws through the two holes in each flange (4 in total); on a metal or thick base, M8 bolts can be used through the slots instead.
- Details
Fix it from below with 4 screws. The upper brackets move with the armrest.
- Details
Cut a slot for the arms of each mechanism (2 slots). The arms must travel in the slots without catching; there is no intermediate plate.
- Details
Pull it in and push it fully out; then lift it: it should lock at 15°, 30° and 45°, unlatch at 60° and return to 0° when lowered. The two mechanisms work together.
