Prevent leaves and debris from entering the pipeline with the 6 in. Square Drain Grate with Low-Profile Adapter Drain. The flared-out design has 14.4 sq. in. of open surface area and 44 GPM flow rate—more open surface area and flow capacity compared to a grate that matches the pipe diameter. Ideal for capturing moderate flows from lawns, landscaped areas, patios, walkways, and under downspouts. The 6 in. Square Drain Grate with Low-Profile Adapter Drain fits 3 in. & 4 in. sewer and drain pipes & fittings, single-wall corrugated pipes, and triple-wall pipes. Grate made of high-density polyethylene (HDPE), low-profile adapter made of high-impact polystyrene (HIPS) treated with UV inhibitors.

Applications:

  • Protect your drainage system by using a grate and low-profile adapter on top of drain pipe to block debris from entering and potentially clogging the pipeline while letting excess surface water flow through
  • Ideal for draining moderate water flows from lawns, landscaped areas, patios, walkways, and under downspouts
  • Works with connected drain pipe to capture and convey excess surface water for proper release downstream

Features:

  • Grate top is 5-7/8 in. square with ¼ in. grate openings; Low-profile adapter is 2-1/2 in. high, top opening is 6-3/16 in. square
  • 6 in. Square Drain Grates (with Low-Profile Adapters) are available in a variety of colors and materials
