On-Stage TMP-LSA7700P u-mount Lighting Arms For Stands

The On-Stage TMP-LSA7700P u-mount lighting arms are built for production teams and venue technicians who need to expand fixture capacity without adding another stand. Each arm attaches via a u-mount clamp that accepts any tube diameter from 1.38" to 1.5", making them compatible with virtually every lighting stand on the market, as well as speaker stands already positioned on stage. This versatility eliminates the need to dedicate separate stands solely to lighting rigs, a practical advantage in space-limited venues and touring setups where trimming stage footprint matters.

The braceless arm design keeps the bar clear from end to end, so mounting points are never blocked by structural cross-members. That openness supports up to six additional PAR cans or LED fixtures per stand. Heavy-duty aluminum and steel construction provides a 15 lb per arm capacity, which covers both lightweight LED wash fixtures and heavier conventional PAR cans. The arms can be mounted at any height on the stand shaft and rotated 360 degrees, giving lighting designers fine control over beam angles and coverage without repositioning the stand itself.

For installed venues, touring productions, and temporary event rigs, the simple clamp-on mechanism keeps setup and teardown efficient. Six mounting wingnuts are included, so no additional hardware is needed to start deploying fixtures immediately after unboxing.
