Frequently Asked Questions
What is the purpose of a dog assembly?
A dog assembly is used to securely clamp and seal watertight doors, hatches, and scuttles on ships. The handle and square shaft work together to engage a dog socket, creating a watertight seal under pressure.
What materials are these dog assemblies made of?
They are made from AISI 316L marine-grade stainless steel, which offers excellent resistance to saltwater corrosion and is ideal for long-term offshore use.
Are these dog assemblies compatible with existing marine doors?
Yes, they feature standard dimensions and a universal square shaft design that fits most marine dogging systems. Always verify shaft size and length against your specific door or hatch requirements before ordering.
How do I install a dog assembly?
Each assembly comes with a mounting template and stainless steel fasteners. Align the dog over the mating socket, mark the hole positions, drill, and bolt into place. Ensure the shaft enters the socket fully for proper sealing pressure.
