Floor-Concealed Door Closer
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.
