3. Pre-loading
The best way to use screws and bolts to secure a bracket to the extrusion,
is by "pre-loading" loading them.This simply means that before even bringing the bracket near
the extrusion, we insert all the screws that will be going through the extrusion, onto the bracket.
1) Make sure you know which side of your
item will be facing the extrusion.
3) Just barely "finger start" the
nuts onto the backs of the
screws. It should be loose.
6) You can now slide along the extrusion.

2) Thread the screws onto your piece with the
screw heads on the extrusion facing side.

wiggle room
4) Do NOT thread all the way.
Just enough so that the nut hangs
on to the end.
7) Once piece is placed, tighten the screws.
5) Thread the screw heads of your
piece onto the extrusion. Slight
wiggling will help the screws line up.
