Orbit 37056 3/4 X 4 Inch Cut Off Riser Sprinkler Extension

Product Description

The ORBIT IRRIGATION PRODUCTS INC 37056 is a 3/4-inch by 4-inch cut off riser designed to raise gear drive sprinkler heads to the correct operating height. Made from durable plastic, this riser can be trimmed to any shorter length in the field, giving installers precise control over final head elevation without returning to the supply house for a different size. It threads onto standard 3/4-inch risers and provides a stable, leak-resistant connection in both residential and light commercial irrigation systems. Irrigation technicians and landscaping pros rely on this type of riser to fine-tune head-to-grade alignment after trenching and backfill.

The 37056 riser is suited for use in pop-up gear drive sprinkler installations where the head needs to be elevated above grade or above an existing riser stub. Typical applications include residential lawn irrigation zones, commercial turf systems, and retrofit installations where existing pipe depth does not align with the target sprinkler height. The cut-to-length design eliminates the need to stock multiple fixed-height risers on the job.

Key Features

• 3/4-inch by 4-inch sizing accommodates standard gear drive sprinkler head connections
• Cuttable plastic construction allows field trimming to any required height below 4 inches
• Connects to 3/4-inch risers for straightforward in-line installation
• Lightweight at approximately 0.05 pounds, reducing handling fatigue on high-volume installs
• Durable plastic resists corrosion and soil contact degradation

Compatibility

Designed as an OEM-style replacement and extension riser for residential and commercial gear drive sprinkler systems using 3/4-inch riser connections.

Installation Notes

Installation is performed by irrigation technicians or landscaping professionals. Shut off the irrigation zone valve and relieve line pressure before threading the riser into place. Use thread seal tape on all threaded connections to prevent seepage at the joint. If trimming to a shorter length, cut squarely with a riser cutter or PVC-rated utility knife to ensure a clean seating surface for the sprinkler head.
