Matthews 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.
Matthews C Clamps are manufactured from premium drop forged steel. It should be noted however, that since the Matthews clamp is an adaptation of a standard C Clamp, there is no effective warranty on the part.
