14x14 Rubber Channel for 25x21 Slotted Tube

Description

Where would you normally use 14x14 Rubber Channel for slotted tube?
With a stainless steel glass balustrade, the rubber channel fits into the slot in 21 x 25 slotted tube, so that the glass rests on the rubber rather than the stainless steel.

Which slotted tube does the 14x14 profile go with?
SST203 - Single Slot 21x25 Rectangle Tube.

How does the channel fit to the tube?
A bead of silicone on the base of the slot before pressing the rubber channel into the slot, should be enough to create a nice bond.

PLEASE NOTE : 1 metre of rubber is more than enough for a 2.9 metre length of slotted tube, and about the right amount for a 5.8 metre length of slotted tube.
The reason why this is the case, is that the rubber is not designed to go along the whole length of the tube, rather it is designed to be cut into small pieces (of about 100mm/10cm) and spaced out at about 500mm/50cm increments.

Can it be used for exterior applications?
As it is UV resistant it is more than suitable to be used inside or outside.
