Simply screw the provided screws through the unit
(at the pilot holes) and secure to your mounting surface.
Please check your screw size depth to ensure the provided screws will not go
all the way through your mounting surface.
Also, don't use a power drill or screw gun, unless you know how to set the
clutch so that the screws wont go in too tight and split the support rails.
A great and affordable solution for you, is just an e mail away.
