Any number of these paintable 50mm / 5cm / 2" sections may be added to the following products to enable easy wall installation for the following products:
Each Liner is 50mm / 5cm / 2" long, so if you need a 20cm tunnel, you'd need 4
They can be cut down, so for instance if you needed a 22cm tunnel, you can buy 5 and cut one down by 3cm
We advise that you can add a thin bead of sealant between each liner to create a moisture resistant tunnel, and a wrap around the outside of the joint with duct tape means the tunnel stays solid and is much easier to handle
