Deltana BTC20 Ball Tension Catch 2-1/4" x 1/2"

The BTC20 is a light-duty ball tension catch. It's meant for cabinet doors, closet doors, and other lightweight doors that just need to stay shut, not for a door carrying any real weight or an entry that needs to lock. Tension is adjustable, so you can dial in how hard the door has to be pulled to release. If the opening needs security or holds a heavy slab, this is the wrong part.

The BTC20 measures 2-1/4 x 1/2 inches. That half-inch dimension is what governs your mortise pocket in the door edge or jamb, so a narrow cabinet stile or a thin closet door frame needs to be able to take it. Lay the catch on the edge before you route to confirm the 2-1/4 inch run clears your hinges and any existing hardware.

Mounting hardware is in the bag. Each BTC20 ships individually poly bagged with its mounting hardware, sold one per unit, so a single order covers a single door. If you're doing a run of closets, order one per leaf.

Nine finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. PVD Polished Brass is the one to pick if you want the brass tone to hold up without regular polishing; standard Polished Brass is the traditional lacquered look. For a fleet of closets or a whole cabinet run, pick one finish and stick to it, since the catch is visible on the door edge when the door is open.

Solid brass throughout, in every finish offered. That matters in two places: a humid bath or coastal install where a plated steel catch corrodes and stops releasing cleanly, and a catch that gets cycled hundreds of times a season, where brass wears rather than rusting.

Yes, and the difference is how they hold. A ball tension catch like the BTC20 grips mechanically, with a spring-loaded ball seating into a strike, and the tension is adjustable so you can set the pull force. A magnetic catch has a fixed pull you can't tune. For a closet door in a rental or a corridor where doors get bumped, an adjustable mechanical catch lets you tighten it up on the doors that keep drifting open without swapping the hardware.

Deltana rates the BTC20 for commercial use. On a commercial job it belongs on the same openings it belongs on anywhere: cabinet doors, closets, and other lightweight doors. It is not a latch for a rated or egress opening.

One catch per leaf. The BTC20 is a single catch and strike acting on one door edge, so a pair of doors takes two, one on each leaf. On a taller closet door that flexes at the top, some installers run a second catch up high; nothing about the catch prevents it, and each unit ships with its own mounting hardware.
