Fireco "Compact Masts" are similar to the Partner masts, but they are fitted with special collars that reduce the retracted height of the mast. A Compact mast is approx 12% lighter than a Partner Mast. The Compact mast has the same extended height as the Partner Mast, but the retracted length is reduced by approx 13mm per section.
For example a STANDARD CS.3434.N Partner mast has an extended height of 4.440m and a retracted height of 1.583m. A STANDARD CS.8434.N Compact mast has an extended height of 4.440m and a retracted height of 1.531m.
