Member Reviews for Black Diamond Black Diamond Magnetron Gridlock Carabiner

Black Diamond Black Diamond Magnetron Gridlock Carabiner

A revolution in auto-locking design, this biner uses 2 independent magnetic arms in the gate and a steel insert in the nose to lock it closed. Opening it requires 2 independent actions, but you can do it with your right or left hand. It may sound dodgy, but the mechanism is actually super-secure.

Wow,... WOW

Wow, I picked this locker up, in Canmore (as per the usual Edmonton mec store not stocking anything new,innovative or useful for climbers) on a climbing trip. I have to say its awesome! You can look at the carabiner and see that it's closed in a visual of your belayer. It requires no fumbling around to close the locking portion of the gate, and just looks cool.
Pros: Simple
Cons: there are really none

I really wanted to like this carabiner. I mean come on, it's pretty hot looking and the magnet feature is... well magnetic. But sadly it just doesn't quite cut it.
For the last climbing season both my partner & I have been using DMM's BelayMaster biners and I was looking for something with a similar divider to prevent cross-loading and to keep the biner oriented on my harness while belaying, but quicker to employ. The BelayMaster works well for the task but being a traditional screwgate is a bit slow and the black plastic divider is awkward when the biner is not in use.
So enter the BD Magnetron Gridlock... well on first look it seems like it would solve the BelayMasters shortcomings - but instead it shows the DMM biner's strength, simplicity.
If you're using the Magnetron Gridlock for consecutive belaying say at a gym or in a multiple top rope situation then it works great. You keep it on your belay loop and the locking gate works fine. It's fast and simple to use.
BUT if you're climbing multiple pitches and removing the biner repeatedly from your harness to gear loop it is a total hassle. Why? Because it takes two gate opening actions to remove the Gridlock: one to slip the harness belay loop out of the bottom section and a second opening to take the biner off the loop altogether. Do this twenty or thirty times a day and it starts to feel like a bind.

so quick and easy

Date:November 22, 2012
It is so easy to open and just let go to close it and lock by itself. I foresee myself becoming lazy compare to its previous brother the gridlock screw gate. The time you spent closing the gate with one hand is gone. Yes it is heavier by 2 g but you can always buy lighter locking biner with screw gate. It is up to you. Like the screw gate gridlock, its shape guarantees that it will not be cross loaded with any belaying device. I use mine with the second generation Grigri but also refresh from time to time with an ATC, plate, tube or figure 8. One big con is the cost, very expensive. Hopefully the price will drop over the years. I also throw it into the dirt to see how much accumulation around the magnet (only on the two trigger) will remain and must say they were clean except for a thin layer of dust all over the biner as it would be on any biners. I also let my friend used it and he throw it into a mud patch. He mentioned some of the mud clunk around the biner end of the loop (steel insert) but he just cleaned it with his hand and was back in business. I challenge anyone to do the same with a screw gate and see what happen when you close it. I tried to push the steel insert to see if it wiggle or come off to no avail. Another plus its nose is snug free in all direction so the rope will not get stuck as you try to push it in or out. So overall, yes it would be fantastic except for the exhibitive cost. I am just wondering how well it will do over the years. The magnetron gridlock is a big biner but it is easier to insert the rope. The company seems to have great difficulty to deliver them on time and sufficient quantity.
Pros: Rugged, Simple, so quick
Cons: Expensive, Heavy
