The shelf has a collection trough running the length of the front of the shelf which serves the dual purpose. When installed as a locker bottom, the trough will collect any water which may pool in the bottom of the shelf from melting snow on boots or other spills. When installed as a locker shelf, the trough is ideal for containing pens, pencils, etc.
Standard 4-, 5-, 6-, 8- and 9 tier box locker doors have a padlock hasp and a friction catch. Available at extra cost is a spring-loaded catch. Both 2- & 3 tier lockers have horizontal frame members welded between the doors for added strength and security. 24” wide lockers have full width doors. If slope tops are required, use hoods. All Invincible II lockers accept built-in locks or padlocks and have rubber bumpers on the latch hooks to reduce noise.
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
