The guide (20) includes a movable spacer bar (22) which extends towards the wire feeder (18).

A spacer (12) has a first spacer (12a), a second spacer (12b) composed of a resin, and a third spacer (12c) composed of a resin.

The strap (52) is looped around the beam (48) and a transverse strut (56) of the base frame (12).

The attaching means (27, 30) grasp a fillet (26) located on the underside of the connecting bar (10).

An optional center back brace (13, 14) can be attached between the upper crossbar (3) and the lower crossbar (7) for additional support and weight.

The variable length standoff assembly includes a connector bar to which one or more variable length standoffs can be attached.

The second spacer (132) correspondingly urges against the first spacer (131).

A transparent spacer overlies the fixed-position electrode, and an induced absorber overlies the spacer.

Each variable length standoff can be rotated about the connector bar, and can be extended or shortened to a wide range of lengths.

At least one strut (7,8), which runs the length of the flight bar, connects two lateral walls (3,4) and covers at least one corner, is configured on the interior of the flight bar.

Each first strut defines a curvilinear path different from that of each second strut.

One or more spacers extend between the retainers and each define at least one passage in which a floor rebar can be received.
