Note:
Pull all wires through conduits before mounting the base. See Electrical Planning for
wiring requirements.
When installing the Portal TI frame, it is recommended that the concrete pad be
undercut, as illustrated in the figure below. This type of installation provides greater
security. The undercut pad size should have the following dimensions:

To ensure the base is installed at the proper height, the lower cross braces should be
flush with the concrete surface (the braces are located 6 in. from the bottom of the
frame). Ensure the base frame is level and place the plastic base cover over the
frame after the concrete has set.
