The ER3 has a max bend depth of 4”, where these metal benders can bend depths up to 14 3/8”. Additionally, with the rollers, you can adjust for different thickness/different materials which our current ER3 roller cannot do.
The low profile tapered roller of the Malco Metal Bender allows you to bend mechanical lock standing seam profiles which the ER3 is not capable of making.
Malco’s Metal Benders are also lighter (in most configurations) than ER3, and the modular nature of the product means they’re a little more versatile, too, for tackling different types of jobs.
