Review: Excelente herramienta
Review: Top of the line handle - Our go-to flat box handle. Adjustable length for every situation. Nice breaking as well. A well thought out flat box handle. Columbia is all we use on the job site. Used almost daily with Columbias 10” and 12” flat boxes. Hopefully Columbia will contact me and let me demo their 5” flat box. Been eyeing it for quite some time but can’t justify the purchase.
