1-1/4" Unistrut Framing
Unistrut's 1.25" metal framing system, also referred to as the Unistrut A-Series, is comparable to its more popular 1-5/8" series, but on a slightly smaller scale. In the 1-5/8" series, all strut channel is 1.625" wide. In the a series, strut channel is 1.25" wide. Both series have their own fittings and hardware, designed specifically to be used with that channel width, though the a-series includes a much smaller variety of compatible fitting and hardware options.
