The BUMPER is fitted with 4 fixing plates for 100 mm casters (not supplied).
It is supplied complete with 6 (3/8" x 1") quick release pins.

Both B1 and B2 BUMPERS are supplied with front suspension plates, for

in their transport position (protected) by two quick release pins.
These pins must be removed to rotate the plates into their operating

The EASE FOCUS software will suggest the optimal rigging point for the
desired result.
For the correct use of the BUMPERS, especially regarding maximum load
and rigging point, refer to chapters 3 and 4.
