ROBERTS IRRIGATION PRODUCTS, INC.
THE RIGHT CHOICE IN MICRO SPRINKLERS

435/436-SPRINKLER

The 435/436 Sprinkler is the traditional favorite of growers seeking a flexible yet reliabile sprinkler for a wide range of applications. Interchangeable nozzles allow easy control of out-flow characteristics-from irrigating "rain droplets" to fine moistening mists. Our use of premium UV-resistant resin and single-moving-part construction give the 435/436 Sprinkler unmatched resistance to wear and mechanical breakdown. The result is just what you would expect from a Roberts Irrigation product: years of cost-effect, reliable performance.

Simplicity in design allows full assembly without the use of tools. Spinkler base is available in two basic styles to simplify conversation of existing systems and to give you flexibility on first-time installations.

Use the 435/436 for propagation misting and light overhead watering in the greenhouse, or swap nozzles to create the ideal droplet size for your outdoor nursery applications. And the 435/436 can easily be inverted to accommodate low rooflines which demand a low-arc spray pattern. Orchard and grove growers can deliver a range of uniform rain-type droplets on even terrain, hillsides, or heavy soil. And lanscapers can easily find a nozzle that's right for any hydroseeding, slope planting, or groundcover job. All of these applications are covered by just four nozzles, which can be quickly changed by hand-there is no need for special tools, glue, or additional fittings.
