If your gun holder is constantly exposed to sun, rain, or mud etc. or commercial use (e.g. hunting preserves), Rugged Gear recommends replacing the Velcro straps on an annual basis or sooner, if upon inspection of the Velcro it is showing signs of wear.  The kit includes 8 pieces of vecro to replace the velcro on all four hooks of a 2-Gun Floor Mount gun holder.
