Why “5B”? Because it takes five separate bushings and bearings to keep every moving surface in tolerance and eliminate every metal-on-metal interaction. Wrapped around a three-quarter-inch spindle, it might be the coolest part of our screen system.
Key features
- The exterior casing is not injection-molded, so we can hold perfectly collinear surfaces with the roller tube. That removes any wiggle or rocking in the assembly.
- Parts are machined to +0.000 / -0.005 tolerances. Our machinist likes to brag that this solid stainless steel part will outlast the building it is installed on.
- Alignment marks on the casing help your installer dial in perfect fabric alignment.
- No screws, adhesives, tapes, glues, wedges, shims, or luck required for a lifetime fit to the roller tube. It just works.
