I had one new’ish roof tile come loose after a nasty thunderstorm that had tornado strength winds. I didn’t want to pay someone $$$ just to reaffix one lousy tile so I figured buying my own proper gear will pay for itself. I’m an old school rappelling guy so decided to update and upgrade the kind of gear that’s now available on the market. This carabiner with its anti cross tangle slot is pretty nifty and was very simple to use. Not like the old style D-ring carabiner I utilized in the Army, this one is quarter of the weight making it pretty lightweight. The small slot at the bottom of the carabiner I attached to my suspension harness and the larger open portion I hooked it to a Black Diamond super 8 belay rappel device. Not like the old heavy duty military grade carabiners I used this one having the locking screw device takes the guess work out and adds an extra measure of security. Nothing worse than dropping like a sack of potatoes if you hook up wrong lol. So, got everything together correctly and showed my wife how to be a belay person while I was on my roof, which is pretty steep. Got the tile reaffixed safely with zero injuries so all is good. I liked this lightweight carabiner that’s just the right size for most rappelling and climbing ropes, so I ordered another one to build a second kit. Always have a backup for “just in case”… Review: Excellent belay carabiner - Standard carabiners are just fine for normal or sport use but this does up the game when belaying. With a standard carabiner and a normal belay device there is always the issue of cross loading the carabiner when there is any slack in the system. Even after just a couple uses the advantages of this gridlock design is clear. Keep the harness in the small portion of the carabiner and the belay device in the larger portion and it is all but impossible to cross load and keeps everything neat and tidy. While I do prefer the screwgate design over a twist lock for security the threads on the gate are pretty squeaky and could use to be smoother, but functionally the lock works fine and it's not very noticeable. I would definitely recommend this as a second carabiner and dedicate it to belay use. There are other situations where it could be used but when belaying it really shines. ## Features - BELAY-LOOP ISOLATION DESIGN: Unique GridLock shape keeps the belay loop securely separated from the spine of the carabiner, preventing cross-loading during belays. Enhances safety and rope handling efficiency. - RELIABLE SCREWGATE LOCKING: Manual screwgate closure offers secure, dependable locking for belaying, anchor building, and rappel setups. Provides tactile, controlled operation for climbers and instructors. - KEYLOCK NOSE FOR SNAG-FREE CLIPPING: Snag-resistant nose eliminates catching on harness loops, slings, or belay devices. Ensures smooth transitions when setting up or cleaning systems. - HOT-FORGED ALUMINUM CONSTRUCTION: Strong yet lightweight build withstands the demands of daily gym use, outdoor climbing, and multi-pitch belays. Engineered for lasting durability without unnecessary weight. - IDEAL FOR TOP-ROPE, SPORT & MULTI-PITCH: Designed to optimize belay safety and performance for climbers of all levels. A trusted locker for gym belays, cragging, guiding programs, and personal anchor setups. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B019NUQ48E | | Best Sellers Rank | #75,219 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #56 in Locking Climbing Carabiners | | Brand | BLACK DIAMOND | | Brand Name | BLACK DIAMOND | | Color | Black/Red | | Customer Reviews | 4.8 out of 5 stars 535 Reviews | | Included Components | Black Diamond Gridlock Screwgate Locking Carabiner, Black/Red, One Size | | Item Dimensions L x W | 14.37"L x 1.18"W | | Item Type Name | Black Diamond Gridlock Screwgate Locking Carabiner, Black/Red, One Size | | Item Weight | 76 Grams | | Lock Type | Screw Lock | | Manufacturer | Black Diamond | | Material | Aluminum | | Material Type | Aluminum | | Shape | B-Shape | | UPC | 793661287124 | | Unit Count | 1.00 Count | | Warranty Description | Warranty | ## Product Details - **Brand:** BLACK DIAMOND - **Color:** Black/Red - **Item Weight:** 76 Grams - **Material:** Aluminum - **Shape:** B-Shape ## Images ![Gridlock Screwgate Carabiner | Isolated Belay Loop | Keylock Nose | Secure Belay Carabiner for Rock Climbing - Image 1](https://m.media-amazon.com/images/I/61n+2qYIhSL.jpg) ## Available Options This product comes in different **Color, Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Worked great *by J***S on September 8, 2024* I’m a former 101st Airborne Division veteran that was an infantryman and Air Assault (rappelling and helicopter operations) qualified.
