Hilman OTB/NTB/TB Series Individual Rollers
OTB/NTB/TB Series Rollers are nearly identical to their OT/NT/TB counterparts with the main difference being the addition of two end-blocks on either end of the roller frame.
- The end-blocks have a drilled and tapped hole pattern that allows for the addition of an external guidance system (Accu-Roll).
- In many cases, guidance systems can be interchanged.
NOTE: There are some dimensional differences in the top plate from the OT/NT/T counterparts.
