SMC Large Steel and XL Steel
UL Classified to NFPA 1983 - General Use

Designed for rescue, SMC's Large D and X-Large Locking D Carabiners have been proven performers for many years. The gate opening on the Large D's fits over the railings of most stretchers. The gate opening on the X-Large D fits the rungs on most fire service ladders and stretchers that require a larger carabiner than the Large D. Gates and sleeves are constructed of stainless steel for higher strength, smoother operation, and better resistance to corrosion. Sleeves lock on the gate to prevent jamming or vibrating loose.

Note: 3 Sigma MBS is a standard way of determining minimum breaking strength yielding results that are 99.87% accurate.
