Product Description

Red Heavy-Duty Fire Sprinkler Head Guard for horizontal pipe ends fastens directly to fire sprinkler system piping, providing unmatched protection against mechanical damage. This sprinkler accessory clamps to horizontal pipe, and may be used to protect:

  • Elbow-mounted pendent sprinkler heads at a pipe end
  • Elbow-mounted upright sprinkler heads at a pipe end

Selection and Sizing

This red head guard installs over the top of an existing sprinkler or head guard located at a pipe's end. Each heavy-duty headguard is available for four pipe sizes, including:

  • 1 1/4" (31.75 mm)
  • 2" (50.8 mm)
  • 2 1/2" (63.5 mm)
  • 3" (76.2 mm)

These measurements reflect the nominal diameter or size (NPS) and not the pipe's outside diameter. To guarantee correct sizing, follow these steps:

  1. Wrap a string around the pipe as tightly as possible.
  2. Mark the points on the string where the two ends touch.
  3. Measure the distance between the string's two marked ends to get the pipe's circumference.
  4. Find your pipe's nominal diameter with the chart below.

Ordering and Shipping

Heavy Duty Head Guards are made-to-order and do not qualify for returns. A representative from QRFS will contact you after you place your order to ensure proper sizing and design before placing an order with the manufacturer. On average, products ship five business days after placing an order with the manufacturer.

Additional Details

Each extra-large fire sprinkler head guard makes installation and removal easy with a jig-assembled clamp that installs to the end of a horizontal metal or plastic pipe. Made from hot-rolled mild steel, each guard is designed to provide heads with a large "crush space" that stops or slows the impact of construction equipment, pallets, basketballs, and more.

Red Heavy-Duty Fire Sprinkler Head Guard for horizontal pipe is ideal for use by contractors altering or renovating facilities where unwanted sprinkler activation is especially costly, including cleanrooms, semiconductor facilities, and industrial storage facilities.

This head guard is designed for use as a temporary fire sprinkler guard and is not specifically listed or approved for permanent use with NFPA 13-compliant systems. We recommend consulting with your local fire marshal or other authority having jurisdiction (AHJ) before installing.

Made in the USA!
