Independent snap button adjustments on the paper roll arm accommodate paper sizes from 24" to 30" inch wide. The elastic strap holds your paper close to the table at the opposite end from the paper roll holder. The elastic-band included with your paper roll holder, is stitched in a continuous loop, like a giant rubber band. The tough powder coated finish makes cleaning easy: just wipe with a soft cloth or sponge and mild soapy water. Snap on insertion rods secure the unit to the table.
