C-channel - Table Top Stiffeners
Slots are laser cut into the channel at a length of 1 3/4" per slot, This is to allow a large amount of expansion and contraction.
The channel comes in lengths of 31", 35", 40", 64". If you are require a size that does not match up to any of these you can easily cut them to length using a metal saw.
This is something that we do regularly as our live edge tables come in every size you can imagine.
