Why Buy Duo-Safety Ladders?


  • Over 80 years of experience in the manufacture of the highest quality Fire Service Ladders stands behind each DUO-SAFETY Ladder. DUO-SAFETY's leadership in the field has been won through quality and the long service life of its products.

  • All DUO-SAFETY Aluminum & Fiberglass ladders feature welded and expanded rungs. This two step process makes certain the rung joints are as strong as the ladder beams, and no looseness can develop.

  • DUO-SAFETY Aluminum Fire ladders feature 6061-T6 aluminum alloy, 1-1/4" corrugated rungs and welded rung joints.

  • DUO-SAFETY extension and roof ladder models are all rated for 750 lb. load with a 4:1 safety factor.

  • All DUO-SAFETY Ladders meet/or exceed all applicable standards as established by the National Fire Protection Association for Fire Service Ground Ladders at time of manufacture.

  • We suggest all Fire Departments refer to both the National Fire Protection Association (N.F.P.A.) and the International Fire Service Training Association (I.F.S.T.A.) for complete and proper practices and usage of Fire Service ladders.
