The Smarter Foundation
for Every Sprinkler

LawnLock™ Sprinkler Support is an innovative, heavy-duty stabilization plate designed to prevent sprinkler heads from sinking, shifting, or becoming clogged with dirt and debris.

Engineered from UV-resistant, weather-durable materials, LawnLock creates a clean, stable surface barrier that protects sprinkler performance season after season.

The Hidden Problem Beneath Every Lawn

Sprinkler heads sink, get clogged and ultimately stop working the way they should.

Over time, soil shifts, grass grows over the edges, and normal foot traffic or mowing pushes sprinkler heads below ground level.

When that happens, water coverage becomes uneven and dirt begins to collect inside the head.

Design Components

LawnLock™ Stops the Sink

LawnLock™ creates a stable surface that keeps sprinkler heads at the proper height.

It helps:

• Maintain consistent spray performance
• Keep dirt and grass from interfering
• Extend the life of the sprinkler system
• Reduce service calls and lawn damage

It’s a simple addition that protects long-term performance.

Height-Adjustable Insert

This insert uses a simple sliding design to keep sprinkler heads at the right height without digging or reworking pipes.

It installs directly into your water line and connects to your sprinkler head. During installation, the Riser Pipe is cut so the sprinkler sits at ground level.

If the sprinkler sinks over time, the sleeve lets you raise it back up, up to 2 inches, without digging. Once adjusted, everything stays in place, so there’s no need to replace piping or disturb the area.

How It Works

LawnLock™ creates a secure, ground-level foundation around the sprinkler head using a multi-component support system designed to prevent sinking and debris intrusion.

First, the two-piece Snap Collar locks securely around the sprinkler body, forming a stable base.

Next, the Threaded Top Cover twists onto the Snap Collar, distributing weight evenly across the surrounding soil and establishing surface-level support.

The Optional Cover can then be installed using screws, creating a reinforced barrier that helps block dirt, grass, and debris from entering the sprinkler housing.

Key Features

LawnLock™ is an effective upgrade that protects sprinkler performance from the ground up. By preventing sinking and blocking debris, it helps homeowners maintain healthier lawns with less maintenance and fewer service issues.
