PWQ slide channels can be used for fastening rectangular ducts together.
A slide channel of a desired length is slid over PQ-20 or PQ-30 flange
frame angle sections which are connected with each other.
The slide channel is most often used when the ducts have to be completely
mated along their entire flange frame length and when the clearance over
a ducts is too small to access and tighten KLQ clamps.
