Lock-It Straps is a Sheridan, Indiana–based maker of guitar and bass straps built around a patented locking mechanism that slips over a standard guitar end pin and snaps into place, holding the strap on without requiring aftermarket strap-lock hardware to be installed on the instrument. The retainer is molded from a high-strength polymer the company likens to materials used in ballistic vests and helmets, and the straps are manufactured in the United States.

The line spans several material families, including leather, suede, cotton weave, and polypropylene webbing, sold in widths typically around 2 to 2.75 inches. Lock-It also produces an artist series featuring artwork by psychedelic rock poster designer Bob Masse, with imagery printed on polypro webbing and finished with leather ends. The brand's straps are distributed through major retailers such as Sweetwater, Guitar Center, Musician's Friend, and Music & Arts, and a co-branded cotton weave version is sold through Martin Guitar.

Lock-It Straps became part of the OMG Music portfolio in 2019, joining a group of accessory brands distributed under the same parent. The locking design is the company's defining feature and is positioned as a single-piece alternative to traditional two-piece strap-lock systems from makers like Schaller and Dunlop.

Lock-It Straps has 24 products cataloged on Equipboard, including Straps & Strap Locks.
