Installation TIP - Tubes You Can Use
Author: Grayson Evans
Feeding a ballchain down a wall cavity and retrieving it from a hole in the bottom of the cavity on the opposite side is harder than it looks.

The Problem

It's fairly common to need to feed a ball-chain down a wall cavity from a hole in a wall stud (rather than down from a hole in the top plate). If you have ever tried to do this through a ½ or smaller hole, you'll notice two things. 1) it is darn hard to feed the chain through the hole! You gotta poke it through using something handy off the floor or a screwdriver and tease it in till it falls from it's own weight [I saw guys at the show take 5 min. to do this!], and 2) once the chain is through and down, it will be up against the stud, usually not where you want it.

The Solution

Both problems can be solved by using a small tube to quickly feed the chain through the hole and get it where you want it. The tube can be as simple as a soda straw or a thin- walled aluminum or brass tube from the hobby or hardware store. I'll show you both.
