These aluminum ends are cast from 413 F aluminum alloy, a very strong and resilient material. They are a minimum thickness of 3/16” (.188”) throughout except where extra aluminum reinforcement was cast in where needed. The bronze bearings are pressed into large, machined bosses. The support area for tool box hangers or legs is about 1/2” in thickness. Weather proofing flanges between the lid and base castings mate with one another to form a tight seal to keep the elements out. Our cast aluminum ends also allow a graceful transition with the sheet metal eliminating sharp corners. Also provided on the cast ends are drill bit centering holes that align a drill bit with a pre-existing hole in the reinforced mounting area, so that only 1/16” of material needs to be drilled through. The enclosed instructions indicate which hole to use.
