The RAINBIRD NATIONAL SLS 15SST-C1 is a side strip pattern replacement spray nozzle designed for underground pop-up sprinkler systems. It delivers a rectangular coverage area adjustable from 3 inches by 20 inches up to 4 inches by 30 inches, making it well suited for narrow turf strips, parkways, and tight landscape beds. The 15SST-C1 features a matched precipitation rate, which keeps water application uniform when multiple nozzle patterns are combined within a single irrigation zone. Irrigation contractors and landscape maintenance professionals install this nozzle as a direct replacement on most standard pop-up spray heads.
This nozzle is used in residential and commercial landscape irrigation systems wherever a side strip coverage pattern is required. Typical applications include narrow grass strips alongside sidewalks, driveways, or building edges where a full-circle or half-circle nozzle would overspray onto hardscape. The adjustable coverage range allows the installer to fine-tune the throw distance on site without swapping nozzles. It ships in a package quantity of 25 units, making it practical for contractors restocking a service van or completing a multi-zone installation.
Designed as a replacement spray nozzle compatible with most standard underground pop-up sprinkler bodies used in residential and commercial landscape irrigation systems.
Installation is performed by licensed irrigation contractors or qualified landscape professionals. Shut off the irrigation system water supply and relieve line pressure before removing the existing nozzle. Hand-tighten the replacement nozzle onto the sprinkler body riser to avoid cross-threading or cracking the nozzle seat. After installation, cycle the zone and verify coverage pattern and throw distance before backfilling or closing the valve box.
