MxV knock-out doors use a brush design

Reduce maintenance costs and keep your operations running at optimum speed

MxV’s innovative knock-out design flexes and releases during accidental impact without damaging the door or the track. This knock-out door uses a polypropylene brush (rather than rollers or pins which often need to be replaced) that do not wear or fray. Incorporating a brush design allows the MxV to be knocked out in both directions and reset with ease. MxV is also washable, proving to be the best long-term solution to efficiently seal loading dock areas.

Save energy

MxV’s polypropylene brush seal helps to provide a better U-factor and eliminates costly side gaps that result from door damage, rubber seals that wear, improper installation or door size. In addition, MxV also helps reduce heating and cooling costs, lowering the load required to successfully heat or cool a facility during peak hours.

MxV withstands inward and outward impact forces

Save time and money

MxV maintains workplace efficiency and productivity by minimizing downtime and maintenance costs using its roller-free and pin-free design that withstands both inward and outward impact forces.

Increase safety

MxV’s ease of operation reduces worker fatigue that can be associated with other damaged sectional door panels, rollers or tracks.

To further enhance safety around the loading dock area, add on MxV knock-out door’s optional safety features including an insulated vision panel for verification of truck activity, and a track guard to protect the base of the track which is prone to collision damage.

Optional insulated vision panels and track guards

Insulated panels ideal for food and cold storage facilities

The 3″ thick, UV-inhibited and weather resistant PVC panels of the MxV knock-out door are flexible and insulated. Closed cell polyurethane R-22-rated insulation provides superior environmental separation between outdoor and indoor environments, making MxV the preferred door for food and cold storage facilities.
