the product be overall a good fit , but the bolt be not very long and the include drywall mount and screw be kinda of sad . we get some bigger and longer screw and mount it straight to the ceiling joist , and also use loctite on all of the bolt except the one go directly into the projector . the bolt do not always thread through enough to make I comfortable . the plate itself and the joint be well make and decent though . plus this mount be waaaay cheaper than other , and be customize for the unit .
