Memtech brush industrial weatherstripping has been
designed and field tested as door seals for hot weather
applications – keeping the cool air in and cold weather applications –
keeping the cold weather out. This weatherstripping is used for
all types of door seal applications such as dock levelers, entry
doors, aircraft hangar doors, sectional overhead doors, rolling steel
doors, swinging doors and hollow metal doors as industrial weather strip.

flexible air-tight door seal available for doors and dock levelers. The
technology of brush also serves industry as a deflector on drilling or
surfacing machines, a parts and product guide and a sound or temperature

assembly is normally slid into an aluminum extrusion designed to fit a
particular door or use. The brush can be cut as short as ¼ “ or as long
as 24’ and the extruded holder can be nearly any angle to suit the task
The extrusions holding the
brush are made in several sizes to fit different jobs. These begin with
