The mat clip is made of strong ABS plastic and stainless steel spring, which is not easy to rust and has a longer life
 
Anti-Slip Strong Clamps: The clamp comes with shark tooth clip, which has a stronger bite force, so that the mat will not fall down when you clean it, even if it is heavy duty mat
 
The mats can be hung in an orderly manner, keeping the work area neater and allowing mats to quickly dry to avoid secondary pollution for more professional construction
