We’ve been sourcing whale tail locks from this supplier for over two years now. The zinc alloy structure and corrosion-resistant finish hold up perfectly in the field, even through our Midwest winters. Zero issues with reliability — just great performance.
Danie
These Type I handles have been a solid upgrade to our fleet. The grip is ergonomic, even with gloves on, and the surface finish resists rust very well. We had one unit with a slightly tight latch, but it was easily adjusted. Overall, excellent quality and feel.
Mateo
We use these 304 stainless steel latches on our industrial outdoor storage boxes. Their durability is impressive — no corrosion even after months of rain and salt exposure. The latch action is crisp and secure. Highly recommend.
Klaus
Top-tier stainless steel hinges. We use them on custom trailer doors, and they’ve been through harsh coastal weather without a single issue. The load capacity is more than sufficient and they’re easy to install. Excellent value for money.
Liam
The folding steps are incredibly space-saving and feel stable when in use. We chose the steel version for cost efficiency, and so far it's been reliable across various vehicle types. Slightly heavy, but very sturdy and safe.
