The APMF Universal Projector Mount is one of a kind. We designed this mount to be 100% universal and compatible with all Projectors on the market. The Four Connection Components can be extended or retracted to attach to the mounting holes on the projector. Additionally, some Projectors have only three mounting holes but with this mount, using all four connection components is not necessary. The mounting plate also features a 0-90 degree turn for recessed installation. Our APMF supports up to 65LBS and constructed of 100% High-Grade Steel. If you have high vaulted ceilings, we also have our APMEP Extension Poles which allow you to meet the needs of your personal home/office setup. These poles are 100% compatible with the APMF Projector Ceiling Mount.
