Available in a number of bore sizes, EPT Superior Products offers single split shaft collars, which wrap around the shaft to deliver an evenly distributed clamping force. This gives a tighter match and increased holding power, without the normal shaft damage associated with arranged screws shaft collars.
Indefinitely adjustable and simple to remove, one-piece clamping Split Collar collars are typically used on hard or smooth standard round shafts, more than a split hub or on thin wall tube. By using friction to provide superior grip on pubs and shafts, solitary split collars provide sturdier, more reliable results when compared to the set screw design of solid collars. They also offer tremendous axial power, while minimizing shaft distortion for excellent performance and decreased wear and tear.
EPT’s stainless and black oxide single split collars work well on 
just about any shaft. They’re also long lasting, cost-effective and incredibly simple to use: basically slide the collar into position and tighten the screw to lock it set up.
