This is a replacement latch for an Apache 5800 waterproof box. My son broke the latch on his. It is by no means a fragile item, my teenage son has just put it through a lot of abuse. Dragged across rough terrain, dropped countless times out of the back of our Suburban, tripped over, kicked, peed on by the family dog, you get the point. Through all this the Xbox he carries around in it has remained unscathed. This fits the 5800 perfectly, may fit others with some resizing, not sure.
