The BTS75V floor spring is an ideal closing solution for a door where a larger closer would be unsuitable. The floor spring may be installed in a thin slab concrete subfloor application.
There are a few models of this floor spring available that are designed to cater for a range of functions including non-hold open (for fire door applications), 90 degree hold open and 105 degree hold open (not suitable for fire doors).
There are a variety of interchangeable spindles that add to the versatility of the BTS75V. The variable power size can be adjusted to suit the door which is a great feature to ensure that it’s a perfect fit with your requirements.
The unit is universal/non-handed for pull or push side mounting and has adjustable closing and latch speed and comes complete with backcheck which helps prevent damage to the door and walls.
