At CSS we don’t view ourselves as just another tool supplier.  We carry many proprietary products for the MEP industry that only we stock or have access to in Colorado.  We supply labor saving products from Gripple and Flash, Firestop from Rectorseal and we are one of the last original fastener guys out there…  When it comes to supplying MEP contractors our motto is true:  If we don't have it, you don't need it!
