Our take on the Trimax TRP170 Stainless Steel Round Padlock

The Trimax TRP170 is a 70 mm round padlock built from stainless steel, with a case-hardened 10 mm shackle and an armor-plated key core. Trimax markets it for marine, trailer, RV and powersports use, and the weather-tough body is meant to hold up outdoors. It ships with three keys. At $8.65 at eBay as of November 5, 2026, the best new price sits at the low end of what this lock has recently sold for.

Questions and answers

Is the Trimax TRP170 worth it?
At $8.65 at eBay as of November 5, 2026, it is a cheap way to get a stainless steel lock with a 10 mm shackle. For trailer, marine or RV use, that is a fair trade against brass padlocks that cost more.
How does it compare with a standard brass padlock?
The stainless body resists rust better than brass in salt air and rain. The 10 mm case-hardened shackle is thicker than what most small brass padlocks use.
Will it fit my trailer coupler or hasp?
The body is 70 mm across with a 10 mm shackle, so check the hole size on your latch. It fits most standard trailer couplers and gate hasps but can be tight on small ones.
How many keys come with it?
Three keys are included. Replacement keys are not standard, so keep a spare in a safe place.
When is the price lowest?
The current $8.65 at eBay as of November 5, 2026 is already near the bottom of its recent range. Only two stores list it new, so stock and pricing can shift quickly.
