Quick Overview

REPLACEMENT BODIES ONLY

The BTS80 Series of floor-concealed door closers offer
adaptability to almost any installation.
The closer’s compact body permits its use where a larger
closer would be prohibitive. Versatility allows installation in thin
slab concrete subfloor construction. A wide selection of
interchangeable spindles makes the BTS80 suitable for virtually
any floor covering or threshold application. Because the BTS80
can control exceptionally heavy single- and double-acting doors,
you can incorporate the floor closer into almost any design to
meet most materials, size, and weight requirements.
Trouble-free performance under adverse climatic and traffic
conditions makes the BTS80 floor-concealed closer
dependable and a perfect choice for even the most rigorous
applications. For total control and uncompromising creativity
for any door opening, specify a BTS80 floor-concealed closer.
