Frequently Asked Questions

What is a dog assembly used for?

A dog assembly is used to secure watertight doors, hatches, and access panels on ships and offshore installations. The handles rotate the male threaded section to engage with a mating bracket, pulling the door or hatch tightly against its seal.

What material is this dog assembly made from?

It is constructed from marine-grade stainless steel (type 316L), which offers excellent resistance to seawater corrosion and is suitable for long-term exposure in harsh marine environments.

Is the assembly ready to install?

Yes, the unit comes fully assembled with two handles and a threaded shaft. For installation, it can be mounted directly onto the door or hatch using an appropriate weld-on pad or via a through-bolt configuration, depending on your existing door layout.

Can I replace an existing dog assembly with this model?

Most likely, as long as the thread size and length match your existing door studs. This assembly uses a standard M20 thread, but we also offer other sizes upon request. Always verify the original component specifications before ordering.
