This BLA black nylon heavy duty hinge pair runs a plate size of 80mm x 103mm so you can tackle medium doors and hatches without overbuilding the setup. The 8mm thick plates back up repeated movement in commercial work boats or service trailers where gear cops daily use. The contoured profile clears sharp corners around 80mm wide panels so boots and hands stay away from nasty edges. The hinge body uses UV stabilised black nylon at a measured 8mm thickness so it can sit in full sun day after day. Stainless steel pins run the full 103mm length to keep the action consistent under load. The nylon and stainless mix shrugs off spray and grime better than light gauge mild steel. Sold as a pair, this kit gives a smart buy option when you want matched hinges ready to bolt straight onto your existing gear.

Q: Are these hinges suitable for outdoor marine use?

Yes, these hinges are suitable for outdoor marine use. The plates are made from U.V. stabilised black nylon which holds up under strong sunlight on open decks. The hinge pins are stainless steel so they resist rust around saltwater. The combination works well on lockers, hatches and doors that sit outside all year. Regular rinsing with fresh water will help the gear last even longer.

Q: What is the thickness of the hinge plates?

The hinge plates are 8mm thick. This 8mm thickness gives good support for medium sized doors and hatches. Thicker plates spread the load around the fixing screws more evenly. That helps reduce flex and movement over time. For many commercial or trailer setups, 8mm plates offer a solid balance of strength and weight.

Q: How many hinges are included in one purchase?

One purchase includes a pair of hinges. The hinges are sold as a matched set of two so you can mount both sides of a door or hatch. A pair keeps alignment consistent because both hinges share the same 80mm x 103mm dimensions. This also saves time on sourcing a second hinge. You only need one pack for most standard single door setups.

Q: What size doors or hatches suit the 80mm x 103mm hinges?

These hinges suit small to medium doors or hatches. The 80mm width works well on narrow frames where space is tight. The 103mm length gives extra support compared to shorter hinges of similar width. Many locker lids and service doors on boats or trailers fall into this size range. Always match the hinge spacing and screw pattern to the frame you are working with.
