What are C-Channels?
A C-channel is a steel bar that, when looked at from a certain angle, is shaped like a C. There are slots in the bar so that the C-channel can be bolted into the wood.

So what are C-channels used for? In short, they reinforce tabletops to help prevent cupping and warping. You’ll install them on the underside of the tabletop. There are several handy step-by-step tutorials available on YouTube - they’re worth checking out!
What makes our C-channels special?Back in the day, you’d have to purchase your C-channels from a metal shop, and laser cut the slots yourself. For many woodworkers, that’s impractical. Our C-channels help to eliminate that problem.
We started by ensuring that our supplier had a number of different C-channel lengths available. We carry 4 different C-channels sizes: 31”, 35”, 40”, and 52”. These C-channels are 2” wide with a 1” total depth and a ¾” wing depth.
Cutting the slots yourself is a chore, so all of our C-channels have pre-cut slots; they measure 1 ¾” in length. This allows for expansion and contraction without putting the structural integrity of your tabletop at risk.
We’ve also opted to use C-channels made out of high strength steel with a powder coating. This gives our product a hard wearing finish - our C-channels can take a beating and still look great.
Perhaps best of all, our C-channels are proudly made in Canada.
C-Channel Prep Tips
Before using the C-channel, you should clean it with acetone. This is actually the best practice for any metal you’re going to incorporate into your woodworking - it helps get rid of any dust, dirt, and oils that might have accumulated on the metal.
We also recommend using at least 2 C-channels per tabletop. For especially large tabletops (8 feet and longer), we recommend using 3 C-channels.
To save time and headaches, you might consider using a C-Channel Jig. Use this CNC cut plywood jig to easily install your C-Channel table stiffeners. Simply clamp down and use as a template guide with a 1/4" spiral bit & 1/2" (Outside Diameter) bushing.
