Rated 5 out of 5 by from Best on the Market This is so easy to fit Many features previously unknown before purchase Well worth considering for safe holding back a fire door it even tests and resets every day to avoid being left open - in case of fire it automatically releases door to close on the fitted door closer!

does the floor plate come with it

Asked by: bkay

How far down will the locking bar go?

Asked by: Gramo
Hi The stopper moves by minimum of 10mm and has an ideal fitting range of 10-15mm to ensure it contacts the floorplate and grips to hold the door open. Absolute maximum movement during setting cycle is 20mm but the stopper retracts back in final seconds of setting the foot pedal. Thanks Union Consumer Team
