the mount system work just as you would expect , or better . the installation process take less than 30 minute , and it could not be much simpler . I live in a place build in the 1970 's , so I have 8 ' ceiling as be typical of construction at that time . even with a fairly tall projector , sharp dt-510 , I have more than 7 ' of clearance under the projector . it be exactly what I need for my installation .
