Water a greenhouse bed or nursery row from a compact rotary micro sprinkler with a protective black guard frame. The green rotating element sits inside the frame above a red lower socket, so the moving parts remain visible and easy to inspect. This is a single sprinkler head for a small irrigation point; tubing, a hanging line or a ground support must be selected separately for the layout.

See the parts before installation
The exploded view shows the green rotating element, black guard and red lower socket that also appear in the main image. It helps you recognize the assembly when cleaning or checking the head. The pictured pieces illustrate the head construction; the gallery does not establish that a tube connector or anti-drip valve is supplied.

Position the spray around the crop
A greenhouse installation can suspend the head above the plants with a suitable adaptor and tube. Keep the guard clear of leaves, support wires and nearby sprinklers. Run the zone and observe the wetted footprint at the real mounting height before setting final spacing.
Match the lower socket to the supply
Compare the red socket and your intended connector before ordering. Some sellers pair this head style with a barbed adaptor or a threaded fitting; those are different connection choices. The photographed head alone does not confirm an included adaptor or a universal fit to every 4 mm tube. Plan the matching tubing connection, support and filtration for your own line.
Keep the rotor moving freely
Flush the line before connecting a small irrigation outlet. Turn on water gradually and check that the green element rotates without rubbing against the guard. Inspect the pattern while the other outlets in the zone operate; available pressure and mounting height change the result. If output becomes uneven, shut down and depressurize, inspect the head for grit, and restore water only after it is seated correctly.
Sold as one pictured guard-frame rotary micro sprinkler head. The final connector and any tubing, stake or hanging weight are separate unless an individual option explicitly lists them.
