Modular WorkSafe Light performs so well that it makes the competition's modular rubber mats look like fledgling rookies that are still learning the game! Innovative in design, these 3'x3' (91 cm x 91 cm) mats snap in place in only seconds. More remarkably, these modular mats require NO additional attachments. At 1/2" (13 mm) thick, the outer edges are rounded for safe and easy access, WITHOUT the use of ramps and connectors. That's right...with only 1 SKU, you can create a safe, ergonomically designed mat that works in wet, dry, or even greasy environments. Wow, someone must have pushed the Easy button!

How do you rate this product?*

*Required Field

Q: What does GR stand for?

A: GR stands for Grease Resistant.

Q: What types of fluids is the GR compound suited for?

A: The GR compound is best suited for areas with water and dry debris. It is also resistant to boric acid & ethylene glycol.

Q: What does GP stand for?

A: GP stands for Grease Proof.

Q: What is the difference between grease-resistant and grease proof?

A: Grease resistant rubber mats are designed for limited exposure to oils. Grease proof rubber mats are designed for heavy exposure to grease and oil.

Q: Is there edging available?

A: No, these mats have a built in rounded safety edge so there is no need for additional edging.

Q: Can Modular WorkSafe be exposed to liquids?

A: Yes, Modular WorkSafe can be placed in both wet and dry environments.

Q: How do I clean my Modular Modular WorkSafe mat?

A: Use a high-pressure hose (not to exceed 500 psi) and hot water (max 160o F) to rid the mats of oils. For best results use a mild soap or detergent with a pH between 4 and 9, to clean the mats. Do not use steam (unless specifically recommended), degreasers, or caustic chemicals. Do not machine wash or mechanically scrub the mats.

Q: There 2 sides to my mat. Which side do I stand on?

A: The top side of the mat is the side with the horizontal and vertical bars. The underside has circular nubs.

Q: Can you customize a mat to my specific requirements?

A: Yes we can. We offer 3 types of customization:

  • C1- Custom lengths
  • C2- Custom lengths and widths
  • C3- Fully custom (size & shape)

  • The level of customization by product is on the details tab at the bottom of every product page.

    Q: Are the colors shown on your website the exact color I should expect to receive?

    A: No, because monitors vary so there may be a slight variance in the color. If color choice is critical, we suggest that you order a sample. Due to manufacturing processes and material dye lots, color can vary, but our products fall within an industry-standard acceptable variation.

    Q: Do Modular WorkSafe mats pose a tripping hazard?

    A: Modular WorkSafe mats have a rounded safety bevel (sloped edge) on all four sides. This allows for a smooth transition on and off the mat and do not pose a tripping hazard.

    Q: Do your rubber mats smell?

    A: Yes! Unfortunately, that rubbery smell is a feature of any rubber product. The mat should lose that smell over time. If you are planning to install rubber mats or flooring in any enclosed space, please remember that this can slow the dissipation of a strong rubber scent.
