Using with Sennheiser ME66 and 67 shotgun mics. The Rycote rubber mount for the sennheisers supports are at 5cm wide. This Rode has a support placement option at 7cm from each other, so offers better front-back tilt stability. The support size range is for mics 19-22mm diameter. The entire structure is plastic with the base being honeycombed. The screw holes for the shock mounts do have metal inserts. The unit includes a large handled Allen key to attach the mounts. The camera shoe is all plastic and has a standard (3/8"?) threaded mounting hole inside it. The hotshoe attaches to the base with a crosspoint screw so should be replaceable in case of damage.
