[EDIT] I received a very prompt reply back that this company is sending me out a replacement set for my one bum lock! They also suggested I try another (default) code to see if that would make my one work. But either way they're sending me out a new set and not making me return the bum one! Fantastic customer service--I'm extremely happy with them!!
ALB Plus All-Welded Steel Lockers are made from steel for lasting durability and reliable service. Doors close quietly for reduced noise in busy hallways and aisles. Metal lockers have 5-knuckle hinges for strength. Recessed handle accepts padlock for security. Coat hooks included on Single-, Double- and Triple-Tier lockers. Archette and Six-Tier box lockers have friction latch padlock hasp for security. Archette also has a lower bar for hanging coats and clothing. Several locker styles available with Recessed Base, Sloped Top or Both to meet storage needs. Color finish is Light Gray. Dimensions vary per model.
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.
Sloping tops: while most lockers have flat tops, some manufacturers offer the option of sloping tops to their range of lockers. The slope may be of either 30 degrees or 45 degrees to the horizontal, sloping towards the front, and the purpose of this is to make it impossible to store items on top of the lockers, or to make it harder for dust or other debris to accumulate there. This is an important factor in places like food-processing factories or restaurants where hygiene requirements must be met.
