Questions & Answers

Slim Channel FAQs

Common questions about the NDS Slim Channel drain system

NDS Slim Channel is 2-3/8 inches wide and just 1-1/2 inches deep. This low-profile design allows installation in tight spaces where standard channel drains won't fit, such as under door thresholds or in shallow concrete pads. Channel sections are available in 3-foot, 6-foot, and 9-foot lengths.

Slim Channel is rated for Class A (Light Duty) loads, covering pedestrian traffic and occasional light vehicle traffic. It's designed for residential applications like door thresholds, patios, and walkways. For areas with regular vehicle traffic, consider NDS Mini Channel or Spee-D Channel.

Slim Channel offers three decorative grate patterns: standard slotted (classic design with maximum water intake), square pattern (modern geometric look), and chain pattern (decorative interlocking design). All patterns are available in white, gray, and sand colors to match your hardscape.

Yes, Slim Channel is specifically designed for threshold applications. The shallow 1-1/2" depth allows installation directly in front of doors, sliding glass doors, and French doors where water needs to be intercepted before entering the building. The low profile doesn't interfere with door swing or foot traffic.

Slim Channel provides flexible outlet options: the end cap/outlet features a knockout that can be removed for 2" or 3" pipe connections (leave knockout in place to use as simple end cap), and bottom outlets allow mid-run connections for drainage at any point along the channel.

The Slim Channel system includes: 45-degree fabricated elbows, 90-degree fabricated elbows, fabricated tees for branch connections, couplings to join channel sections, end cap/outlets with pipe knockouts, bottom outlets, and anchor clips. All fittings are available in white, gray, and sand.

Slim Channel installs in a shallow trench with anchor clips securing it to the substrate. The clips prevent the channel from shifting during concrete pour or paver installation. Channel sections connect with couplings, and pre-fabricated elbows and tees handle directional changes. Grates snap securely into the channel.

Slim Channel components are available in three colors: white, gray, and sand. This applies to channel sections, all three grate patterns (slotted, square, chain), fabricated fittings, and accessories. Choose the color that best complements your concrete, pavers, or decking.

Yes, Slim Channel is excellent for balcony drainage. Its shallow depth is ideal for the limited floor thickness on balconies and rooftop decks. The lightweight construction adds minimal load, and the decorative grate options provide an attractive appearance for outdoor living spaces.

Slim Channel (2-3/8" wide, 1-1/2" deep) is slightly wider and deeper than Micro Channel (1-1/4" wide, 1-1/8" deep). Slim Channel offers interchangeable decorative grates and handles more water volume, while Micro Channel has an integrated grate and nearly invisible profile. Choose based on your aesthetic and flow requirements.
