TRU-FIT Universal Clutch Plate (NP-9200)

Determining Diameters

Block Diameter: Lay the brush on the bristles, block side up. Measure the actual outside diameter of the block (not the bristle flare). See photo below for reference (measurement B).

Center Hole Diameter: Lay the brush on the bristles block side up. Remove mounting hardware, if any. Measure actual inside diameter of the center hole. See photo below for reference (measurement D).

Floor Machine Brushes, Pads, Drivers & Clutch Plates - Determining Diameters

NOTE: Malish brushes are designed to fit each machine as shown, even though the block diameter listed on the charts may vary slightly from the diameter of the block originally supplied with the machine.

How to Break in a New Floor Machine Brush

Before using a new brush on carpeting, the brush should be broken in according to the following directions. This will eliminate possible excess drag by “tipping” the strands, removing any possible burrs caused by the manufacturing process.

Break-in Procedure

  1. Mount the brush on the floor machine. Follow ALL instructions included in your owner's manual.
  2. Find a rough textured floor surface, preferably unfinished concrete.
  3. Operate the machine on this surface. Run the machine DRY for approximately 15-20 minutes. The brush fibers will take a slight set or lean in the direction of machine rotation.
  4. Rinse the brush to remove any dirt caught when running machine. The brush is now ready to be used on carpeting.

Do you want a brush or a pad driver?

If your preference is to have a dedicated product, select a brush. If you have a variety of applications, your choice may be a pad holder. The surface being cleaned and the amount of dirt build-up will help determine the selection. The key to remember when ordering these items is the block diameter in relationship to the machine size. A brush is sized 2 inches smaller than the machine because of the flare of the brush fibers. Pad drivers are specified 1 inch smaller than the machine.

There is an easy way to cross check your selection from the Floor Machine Brushes and Clutch Plates section of this web site.

  • A brush, long-trim pad driver, or short-trim pad driver without a riser, should be 2" smaller than the machine size.
  • A pad driver or MIGHTY-LOK™ should be 1" smaller than the machine size.

Therefore, a 20" floor machine would use an:

  • 18" brush, MAL-LOK™ or PAD-LOK™ without a riser
  • or a 19" PAD-LOK™ or MIGHTY-LOK™

This rule applies to over 90% of the applications.
