Sugatsune (brand)

Sugatsune catches (ball, roller and magnetic) are precisely made and come in stainless options that keep holding consistently long after cheap stamped catches loosen.

Not for: Anyone who needs a lockable or compression-sealing door closure (use a latch instead), or anyone fitting a large number of light-duty cupboard doors on a tight budget.

Southco V7 (line)

Over-center action provides secure closure for industrial enclosures, with multiple configurations to match mounting and load requirements.

Not for: Applications requiring safety-rated retention without separate verification.

Which one fits you

budget household cabinet doors

National Hardware (brand)

Widely available basic magnetic and roller catches that are good enough for ordinary cupboard doors.

Not for: Anyone fitting heavy, outdoor or marine doors, or doors that are opened constantly.

Check before you buy

Catch type. Use magnetic catches for quiet, simple closure, roller or ball catches where the door must also stay aligned, and touch (push-to-open) catches for handleless fronts. Each type fails in a different way. Magnets weaken with misalignment and ball catches wear their strike.
Holding force. Match the rated pull force to the door's weight and how often it is used, and size up for doors that warp or spring. Too weak and the door drifts open. Too strong and light cabinets rock when opened.
Mounting style. Confirm surface-mount versus bored or recessed mounting, and that the strike suits your inset or overlay door. The wrong geometry leaves the catch unable to meet its strike.
Material. Use stainless steel for outdoor, marine, food or washdown areas, and zinc or plastic only indoors. Plated steel and zinc corrode and stop catching reliably in wet environments.
Adjustability. Prefer catches with slotted holes or adjustable tension. Doors settle over time, and adjustment lets you fix closure without redrilling.

Questions

Catch or latch?

A catch only holds a door closed by friction or magnetism. If the door must lock, seal or resist vibration, you need a latch.
