How to Guide

INSERTING BASE ASSEMBLIES

Pour and ﬁll the hole with concrete to a depth of 4 inches from the top and tap or vibrate the concrete to

ensure it completely settles at the bottom of the hole. Position the base down into the concrete.

1. Align the center line marks on the angle brackets with the line marks on the center edge. (See illustration P).

2. While ﬁlling with concrete, gently tap on the very

center of the top of the base with a block of wood

or handle end of a hammer.

NOTE: Each base is designed with a 3” x 3” hollow square tube. At the very top of the tube and

through its rear wall, just under the threaded plate, there is a 3/4” hole in the tube. This hole allows air to

escape from the inside of the tube while the inside is ﬁlling with concrete. (See illustration O)

Ensure you clamp the center line marks together so that both angle brackets are resting ﬂat on the

surface of the ﬂoor. (See illustration N).

It is critical that the inside of the base is

completely ﬁlled with concrete to maintain

maximum strength.

3. Ensure the top edge of angle brackets are ﬂush with the

surface of the ground.

Do not remove the clamps and angle brackets for

at least 24 to 36 hours depending on the temperature,

humidity and soil mechanics to allow concrete to set.
