Marine Door Hasp Latch with a Separated Fixed Eyelet Block. This three-piece security setup is commonly used on boat cabin companionways, sliding doors, and storage chests. Unlike single-body toggle clamps, this design splits the hinge and the lock receptor, making it incredibly durable and vibration-resistant against heavy sea spray and engine rattling.
180-Degree Heavy-Duty Hinge: The right-side mounting block houses a thick, four-screw barrel hinge. This allows the heavy flat hasp plate to flip completely open and lay flat when you need unhindered entry into a cabin.
Hasp Cutout Window: The large rectangular opening on the left swings directly over the vertical metal loop.
Independent Lock-Eye Block: The lower centerpiece is an independent block featuring a vertical eyelet. When screwed into the matching frame, it rises cleanly through the plate window, allowing you to attach an external padlock to secure the entire vessel door.
Installation Recommendations
1,Preventing Metal Dissimilarity: Because this structure is pure Grade 316 Stainless Steel, avoid installing it with regular steel or zinc-plated screws. Always use matching marine 316 fasteners to prevent galvanic rust.
2,Alignment Pre-drilling: Fix the right-side hinge plate first. Close the door completely, position the left-side cutout over the frame, drop the independent eyelet block into the center window, and mark your screw points precisely so the latch closes smoothly without binding.
To make sure you get the perfect fitment size:
What is the total length of the flap plate from the hinge pin to the opposite tip (most common sizes are 3 inches / 76mm or 4 inches / 100mm)?
Will you be mounting this onto a flat sliding companionway hatch or a swinging cabin door?
