Premiers universal short-throw projector arm is crafted to support all of the latest short-throw projectors on the market today. Offering more adjustability than any other projector arm on the market, the UNI-STB adjusts from 7" to 27" (up to 67" from the wall when ordered as a UNI-EXB). Best of all, it does not require that a stud be located in the center of your whiteboard/screen (which is hardly ever the case). Happy to mount to a single stud or dual studs at 16" , 18" or 24" spacing, the UNI-STB is the most flexible and installer-friendly short-throw arm on the market.Premiers universal short-throw projector arm is crafted to support all of the latest short-throw projectors on the market today.
