Number of locking points: Locker doors may lock with either single- or three-point locking, but this is not normally chosen as a separate option, and the choice is usually dependent on the number of tiers in the lockers, or whether they are a high-security model, although some manufacturers do allow purchasers to specifically choose an option here that goes against their normal practice. Single-point locking locks the door at only the point where the latch engages with the door-frame, whereas three-point locking uses extensible steel rods to lock the top and bottom of the door as well.
I must stay, I was a little reluctant on buying this product because of the lack of reviews, but I am not disappointed at all. This product is EXCELLENT. I was a little overwhelmed with the installation process at first, but after emailing back and forth with the seller they were able to send me step by step video instructions. It was super easy to install and looks great. The individual keys are very well made. Highly recommend it
