The SlideLock Carabiner provides convenient attachment with a locking gate. It&';s the classic carabiner with a Nite Ize innovation!At Nite Ize, they believe no product is too small or basic to be improved. Exhibit A: the classic utility carabiner. Nite Ize took a hard look at this ubiquitous device and saw two good opportunities to make it more efficient. Nite Ize designed an innovative slide-to-lock feature that securely locks the gate with a simple push and slide movement, and unlocks when you want it to just as easily. Then, instead of a bulky tubular construction, Nite Ize designed a cross sectioned, rectangular stainless steel body that&';s durable, low profile, and slim; it feeds more easily through smaller openings and rests flat in pockets.Durable Stainless Steel Locking Utility CarabinerSecure stainless steel wire gate with a slide-to-lock featureDimensions: 1.7" x 1.1" x 0.1" | 43.6mm x 28.9mm x 2.5mm Weight: 0.2oz | 7.0g - Weight Rating: 10lb | 4.5kgNot intended for use in climbing, safety situations, or any other scenario where humans may be injured
