Frequently Asked Questions

What materials are used in these swing door catches?

Our swing type door catches are manufactured from marine-grade zinc alloy with stainless steel springs, and are available with a chrome or brushed finish for corrosion resistance in saltwater environments.

Are these catches suitable for heavy ship doors?

Yes, they are designed for standard interior ship doors such as cabin doors, storerooms, and light-duty watertight doors. For heavier doors, consider multiple catches or a heavy-duty alternative.

How do I install the swing door catch?

Mounting is straightforward: attach the keeper plate to the door frame and the latch unit to the door. Use the included screws or appropriate fixings for your door material. Align the latch with the keeper and secure.

Can these catches be used in outdoor marine applications?

While they are corrosion-resistant, they are primarily intended for interior use. For exterior or weather-exposed areas, we recommend a more rugged stainless steel catch with sealed components.
