This Safety Pro Outdoor Stadium Pad 3 Inch x 4x7 Ft. Z Clip Attachment is made with exterior grade wooden strand board and 3 inch thick polyurethane foam laminated together using a two-part bonding process. The foam and wood material are then wrapped with 19-ounce vinyl on the front and sides and secured with galvanized steel staples to the wood back, for a total thickness 3-23/32 inch. 

Stadium padding with Z Clip attachments makes installing the pads for your outdoor field easy. The clips can be attached to the back of the outdoor wall pads by screwing them into the plywood backing of each panel, and the other side of the clip is screwed into the wall. The advantages are that it conceals the mounting hardware behind the wall pads, and it also eliminates the chance of the hardware causing a safety hazard. The Greatmats Z-Clip wall mat includes all the required hardware.

The exposed wood backer board also has an additional seal coat of a tinted exterior wood primer. The vinyl is treated with UV additives for exceptional UV protection. and with BACshield, making it highly resistant to mildew and fungus.
