About 21" Burnishers

21" is a pad size option within the burnishers category. Pick the right pad size for the area, the user and the work the machine sees most.

How to Choose

Match the pad size to the practical needs of the install or use case. Larger or higher capacity is not always better; the right size for the work runs more efficiently and lasts longer than an oversized unit running short cycles.

Frequently Asked Questions

What is the most popular pad size?

The most popular pad size depends on typical install or use. Mid range options usually cover the widest range of needs without being oversized for compact work or undersized for large jobs.

Can I change the pad size later?

No. Sizing decisions are made at install or purchase. Plan the right size before ordering.

Does 21" cost more?

It depends on the option. Larger sizes cost more in proportion to the additional material. Check the spec sheet for current pricing across the range.
