The Seachoice Grand Slam Non-Locking Latch (Mini Square, 1-3/8 in.) is a compact, corrosion-resistant hatch and compartment latch built from 316 stainless steel for lasting durability in saltwater environments. The full-width handle allows comfortable one-hand operation, while the anti-rattle design keeps hatches and compartment doors quiet at speed — no vibration noise from floor panels or storage lids while underway.
A watertight gasket is included, making this latch a solid choice for floor compartments, livewells, and any hatch where moisture intrusion needs to be controlled. The reversible backing plate accommodates door thicknesses from 3/8 to 7/8 inch, and the adjustable slide allows fine-tuning after installation without re-drilling.
Parts Desk Insights
Best use case: This mini square latch is the right pick when you want a square profile in a tighter space — particularly on smaller hatches or panels where the standard 1-3/4 in. square version is too large. If your cutout is already square and you need a watertight seal, this is the most direct fit. For round cutouts or larger openings, see the related Grand Slam variants below.
- Confirm your cutout shape and size before ordering — this is the mini square (1-3/8 in.) version; the standard square is 1-3/4 in.
- The reversible backing plate lets you flip the latch orientation to match your hatch swing direction without additional hardware.
- Seat the watertight gasket evenly during installation — an uneven gasket is the most common cause of minor weeping on compartment latches.
- 316 SS resists pitting in saltwater better than 304 SS; a good choice for offshore or coastal applications.
