Product Overview

Dimensions

Rain Bird lists a 5-inch stake. The 1/4-inch designation describes the tubing connection, while the 0–3-foot distance is a watering-performance range at 30 psi; neither is an overall device width. Leave the cap above soil and mulch for adjustment and keep foliage clear of the streams.

Compatibility & Installation Notes

Connect compatible 1/4-inch tubing to the barbed inlet and use the included fitting as required by the layout. Flush the supply before connecting the devices and use filtration and pressure regulation suited to the complete drip system. Stake each bubbler securely, then adjust the cap while the system runs and observe the wetted area. Flow and reach change with pressure and adjustment; the 30 psi performance reference is not a stated maximum inlet-pressure rating. Include every outlet in the zone flow calculation and reduce output or split watering cycles if runoff occurs. The manufacturer product guide identifies MBF-4PK as the spiked full-circle model.

Why Buy from Big Frog Supply?

Choose MBF4PK when several small planting areas need adjustable, full-circle watering from a 1/4-inch tubing layout. The four-pack and included 5-inch stakes make placement straightforward, while the 0–13 GPH reference range at 30 psi lets you account for each adjusted outlet in the zone demand.
