The better engineered your Bi-Fold (by-fold) door hardware is, the smoother the operation of your doors will be—over the lifetime of the installation. Smart homeowners, contractors, and architects insist on KV hardware sets and components to ensure trouble-free installation and reliable performance.

We offer a wide range of classic Bi-Fold door hardware sets featuring steel or aluminum tracks in 2- and 4-door configurations. Our tracks accommodate rough openings from three to eight feet and support doors up to 125 lbs.

Bi-Fold door hardware is available in kits (by opening length) or individual components. We also offer bulk volume packaging for distributors and high-volume purchasers.
