Tacky Mat with Frame is a low profile, flat base which is constructed of a rigid PVC and designed to hold sticky mats in place on a variety of flooring surfaces while allowing the sticky mats to be moved to different locations (and thus allowing a sticky mat pad to be used multiple areas without adhering the pad to the floor itself). Sticky Mat Frames have a tacky, non-slip bottom that keeps the frame firmly in place no matter the type of floor the frame is on. The sticky mat themselves trap dust and dirt. The sticky mat's surface is tacky to remove impurities from shoes before they can contaminate the area. Once the top layer is dirty, simply remove & discard. Clean room mats and frames are ideal for hospital, laboratory and construction and even residential use.
