Product details:

The Everest S1040 is a 4 in. x 30 ft. Heavy Duty Commercial grade ratchet tie down. Features Corrosion resistant hardware and flat hooks. The 30 ft. of extra strong webbing gives you reliability when you most need it. This is designed for heavy duty commercial users of truck straps. Aluminum has a very good amount of corrosion resistance in most environments and situations. The reason for this is that aluminum, as a material, forms a very thin but extremely effective oxide layer that works to prevent additional oxidation. The aluminum oxide is resistant, and it sticks very strongly to the parent metal. This is unique to aluminum and aluminum oxide, as other metals that form oxide layers do not adhere as strongly. EDGE GUARD, the extra black stitching for ultimate protection. Everest uses this as added protection from breaking due to abrasion; testing by an independent lab for an aircraft and military supplier shows that after 2500 cycles of the abrasion test the straps will still hold the load. With a breaking strength of 16, 200 lb. and a 5, 400 lb. WLL (Working Load Limit).
