A 400 ML Manual Adhesive Dispensing Gun is required for all Plexus 400mL and 490 mL adhesive cartridges. The Cox M400XMR and M400XMR/10 have a plunger with a 26:1 mechanical advantage that operates on a hydraulic action, creating a smoother flow than most caulking guns.

The M400XMR dispenses the two components of the adhesive in the proper 1:1 or 2:1 ratio. The M400XMR/10 dispenses the two components of the adhesive in the proper 10:1 ratio. With the use of a static mixing nozzle (sold separately), the A and B parts are mixed thoroughly and dispensed properly. This side-loading frame design provides fast, easy, mess-free cartridge change outs.
