The HSA-45 Flash Shoe Adapter from FLM is an adapter that attaches to a clamp, leveling base or tripod on one side and has a cold shoe on the other side, allowing you to add a bubble level, a small ball head or any other cold-shoe mountable accessories. It is made for use with the QRB II clamps, the LB leveling bases and as a replacement part for the CP-30 tripods.
There is a star-shaped screw for attaching the adapter to the clamp, base, or tripod, and another screw beneath the cold shoe for accessories. A bull's eye bubble level attachment is included, but can be removed and replaced with other accessories.
