Available in a number of bore sizes, EPT Superior Products offers solitary split shaft collars, which wrap around the shaft to provide an evenly distributed clamping force. This gives a tighter suit and increased keeping power, without the normal shaft damage associated with established screws shaft collars.
Indefinitely adjustable and easy to remove, one-piece clamping collars are usually applied to hard or smooth standard round shafts, over a split hub or on thin wall tube. By using friction to provide superior grip on pubs 
and shafts, single split collars offer sturdier, more reliable Split Collar results in comparison with the set screw design of solid collars. In addition they offer incredible axial power, while minimizing shaft distortion for excellent performance and decreased deterioration.
EPT's stainless steel and black oxide one split collars work well on just about any shaft. They're also durable, cost-effective and incredibly easy to use: basically slide the collar into position and tighten the screw to lock it set up.
