Master Your Rink Grade with Accuracy Building a backyard ice rink is a game of inches. If your slope is off, you risk thin ice on one end and a blown-out sideboard on the other. Our Heavy-Duty Line Level is the essential tool for determining the pitch of your yard before you lay your liner. Why a Line Level is Critical for Rink Builders Standard levels are too short for the wide spans of an ice rink. A line level allows you to check for levelness across 20, 30, or 50 feet by attaching directly to a taut mason line. This helps you calculate exactly how much "fall" your yard has, so you can choose the right board heights and reinforcement stakes. Product Features Ultra-Lightweight Design: Specifically engineered to hang on a string line without causing sag, ensuring a 100% accurate reading. High-Contrast Vial: Features a bright neon fluid for easy reading during those late-evening builds. Secure-Grip Hooks: Deep-set hooks prevent the level from slipping or falling off the line, even in windy conditions. Weather-Resistant: Durable construction that won't crack or become brittle in freezing winter temperatures. How to Use It: The "Rink-Ready" Method Find the High Point: Identify the highest spot in your yard and drive a stake. Mark the string height at 4 inches. Run Your Line: Pull a mason string tight to a stake at the opposite end of your rink. Level the String: Snap the line level onto the center of the string. Move the string up or down on the far stake until the bubble is centered. Calculate Your Slope: Measure the distance from the level string to the ground. This measurement tells you exactly how deep your water will be at that location. Pro Tip: If your slope is greater than 6 inches, we recommend using our heavy-duty steel brackets on the deep end to support the extra water pressure.
