Code – SPACE/GLI - Click here to enquire The aluminium glider fitting acts like a T- bolt in the tracking. By attaching a seat to the glider, it remains captive in the track (like a fixed seat position) but can be repositioned by loosening the nuts and sliding the gliders in the track. Tested to M1 on a single seat in Smartfloor to meet the requirements of ECE regulation 14 and EU directives 76/115.
