Commercial Track Applications
Commercial and industrial buildings often need to meet code requirements and ADA standards for space.

Clopay track solutions include standard lift, low headroom with a front or rear mount, follow roof pitch lift, full vertical lift, and combination options.

Clopay torsion spring options can be designed for the industry standard of 10,000 cycles or can be upgraded to 25,000, 50,000, or 100,000 expected life cycles.
