MSE C Clamps are available in 4, 6, 8,
10, and 12, with or without 5/8" mounting pins or Junior Receivers.
Each clamp has a steel channel welded to both sides of the opening for
better and safer locking. Clamps made for mounting Baby fixtures have
two separate pins at different angles so that the light fixtures may
fit with minimal clearance. Junior Receivers are made in two fixed
versions Horizontal and Vertical and a Universal Mounting Junior
Receiver which can be used in any one of eight different positions. All
MSE C Clamps are made of forged steel.
