| Black Diamond Rocklock 4.5 out of 5 based on 31 user reviews.
 Cred: 2509 | | great size, moderate weight, works well with all knots and hitches, including munter hitch. It is the indespensible biner. I keep one for belaying, and one extra for rigging. |
| vaporlock is the same thing with much weight shaved off. |
|
 Cred: 601 | | Nice, big basket size for fatty ropes while belaying or using the Munter, clove hitch, etc. Rounded for less friction which is nice during self rescue or while belaying a featherweight. |
| A little on the heavy side. |
|
 Cred: 120 | | at the rock gym i go to it is required to have two of these locked into your harness and then the rope through both of these-
the size of this carabiner makes it really easy to get the rope in and out- |

 Cred: 14 | | Review by zihyer on May. 07, 2008 | | Great locker... smooth gate action but still nice and firm close force. Large to medium capacity and mouth opening are a real plus for housing multiple items. Makes a nice centerpiece to any anchor. |
