Short answer

Surplus Strength sells the UPS Low as an add-on to its UPS High. It fits 3x3 or 2x3 lower crossmembers with a top height of at least 6.75 in, on racks with 1 in or 5/8 in holes, and can go on the side, rear or front. Surplus cuts the 1/4 in cable to the rack height you give in the order notes and states no weight capacity.

Watch out for

  • It is an add-on to the UPS High, not a complete station.
  • The lower crossmember must have a top height of at least 6.75 in.
  • "Universal" in a product family name is not a universal fit. Surplus lists the crossmember sizes, height and hole sizes above.
  • Give your rack height in the order notes; Surplus cuts the cable to length.
