The ModRight Super Large Anti-Static Mod-Mat and Assembly Surface Revision 2 is the first full anti-static mat with enough room to complete your entire assembly on! The oversized Mod-Mat is a huge 1200mm x 600mm which is over 47" x 23". This allows plenty of room to complete your entire build on without worry of static or scratching priced hardware and parts. The anti-static surface is safe for all components including your motherboard, VGA cards, RAM and any other electronic parts. Placing high finish side panels and parts are not an issue either as the non scratch surface will not blemish the finish whatsoever. This Assembly Surface includes both a grounding wire clip and an anti-static wrist strap to ensure proper precaution when conducting your next build. Both straps are connected directly to the Mod-Mat itself so you know you have a solid ground. To make life even easier the Mod-Mat comes in an easy to transport box with a handle. Revision 2 now comes equipped with a fan hole spacing chart so you can check fan sizes on the fly. Inch and millimeter rulers are on the bottom and right side for other handy measurements needs! No computer builder / enthusiast should be without this work surface!
