The Type BR sloped wall basement door is designed for installation on areaways with sloped sidewalls built into a home's foundation. Doors can be installed on sidewalls of brick, stone, block, or poured concrete and are supplied with instructions and hardware for proper installation.

Standard Features and Benefits

  • Easy to Operate... Gas spring operators and supplemental coil springs counter-balance the door leaves for easy, one-hand operation. Lift assistance can be adjusted to match the force required by the slope of the areaway.
  • Weathertight... This sloped wall basement door sheds water, keeps areaway dry and free of debris. Flanged construction sheds water and prevents binding due to ice and snow.    
  • Rugged... Heavy gauge steel and sturdy concealed hinges that are protected from the weather ensure all-season operation and lasting service.   
  • Durable... Baked-on Sherwin Williams primer provides a durable base for finish paint
