Check the fit
Use the 18-foot working length from the exact item and contents. Confirm freight and site access separately because the package dimensions shown do not describe the beam.
When to choose it
The 22-318 gives you an 18-foot working edge and a 1-1/2 by 3-1/2 inch section. It is shorter than Bon’s 20-foot 12-507 and has a different section, so compare both measurements when selecting from the longer tools.

Advice and other choices
Questions about this product
Which number should I use for working reach?
The 18-foot working length. The section figures describe the body across the beam.
Does it use the same section as the 20-foot Bon 12-507?
No. The 12-507 lists a two-by-four-inch section.
What if I cannot maneuver an 18-foot tool on site?
Compare a shorter supported pass with adequate bearing at both ends.
