Cable Protector Plates are simple and inexpensive steel plates that are hammered into studs covering electrical, gas, or water lines that run through walls. The steel cable protector plate deflects nails and screws from penetrating important, but vulnerable cables and pipes. They help remove the danger from electrocution, house fires, gas explosions, and water damage.

It is necessary to run electrical cables, gas lines, and water pipes through walls so services are where they are needed. NZ building code allows these to be placed anywhere in or on the face of the studs or nogs. This places many electrical, gas, and water lines within the reach of drywall screws, trim nails, and longer cabinet screws. All pipes and electrical cables are within the reach of a homeowner that wants to secure heavy shelving, expensive electronics, or prized art pieces with the longest screws and nails that they can find directly into studs.

The use of a Cable Protector Plate protects the wires and pipes contained within the walls. These Plates are an inexpensive and obvious solution to protecting your most valuable asset; both during your build, and for the decades that you enjoy living in your home.

Why Haven't I seen These Before? 

Cable Protector Plates are required by electrical building code of other countries for prevention of damage by punctures.1  Other countries use them for protecting gas and plumbing lines too.

NZ building code requires that all circuits containing outlets and lights be protected by an RCD (residual current device). This protects homeowners from shorts in appliances as well as wires. However, any circuits that don't contain lights or outlets (water heater, stove, hob, oven, etc...) still need to be protected by either Cable Protector Plates or additional RCDs.2

To date, New Zealand has also overlooked protecting water and gas plumbing from puncture damage. However, this disregard doesn't prevent damage, and 'call backs' to repair punctured lines are required. The possible repercussions of these punctures can be very costly or dangerous. Punctured gas lines can result in explosions and fire, and punctured water lines can result in slow leaks that can cause significant water damage.  These could have been easily prevented by using an inexpensive and easy to install Cable Protector Plate.
