Cinch-Lock Wrist & Forearm Splints

When carpal tunnel syndrome, tendonitis, a sprain, or a repetitive strain injury flares up, the wrist needs to be held in a neutral position without a rigid cast that locks out all function. Cinch-Lock splints do exactly that — they immobilize and support the wrist while the cinch-strap closure lets the wearer dial in the exact snugness they need, then loosen it just as easily to reapply or accommodate swelling through the day.

The design centers on one practical detail most buyers ask about: fit. Every splint here is one size fits most adults, sized by wrist circumference rather than by a run of small-to-large numbers, so there's less guesswork. The shorter Cinch-Lock Wrist Splint (79-82470 right hand, 79-82471 left) fits wrists up to 11 inches and uses a single removable palmar stay — the rigid insert that runs along the palm side to keep the wrist from bending. Pull the stay out and you can hand-wash the fabric, or contour it to the wearer's anatomy.

For injuries that need control higher up the forearm, the longer Cinch-Lock Wrist / Forearm Splint (79-87050, 79-87080) fits wrists up to 9 inches and adds a malleable dorsal stay on the back of the hand alongside the palmar stay. Two malleable stays mean a clinician or the wearer can bend the metal to hold the wrist in a therapeutic angle and resist both flexion and extension — useful post-injury or for overnight positioning.

Handedness matters with these, so each model is offered in dedicated left and right versions in navy blue, blue, or black. Order for the affected hand, and confirm wrist circumference before choosing between the up-to-9-inch and up-to-11-inch options.

Comparing closure and support styles across our brace lines? It's worth also looking at CINCH and Soft-Lock supports to match the right level of immobilization to the diagnosis.
