Price and purchase ↓
Check the fit
Compare the actual span, support and access before selecting it. If a shorter beam can bear on both forms, check that option first.
When to choose it
This Bon beam offers a 20-foot working edge in a two-by-four-inch magnesium section. It makes sense only where the crew can bring in that length and guide it over the planned supports.
