Eureka 12" Bottom Plate - S...
$15.99
Product details
The bottom plate on a 12 inch Eureka or Sanitaire upright sets the working height of the cleaning head and seals off the brush and belt cavity from the floor beneath it. Its fit determines whether the nozzle actually seals against the carpet or leaks air along its edge, which directly affects how much suction reaches the brush roll.
Running the nozzle over door thresholds and raised carpet edges is what typically warps or cracks a bottom plate over time, and the mounting tabs holding it in place tend to break first since they are thinner than the plate itself. Once a plate stops sitting flat, the seal goes uneven, brush height drifts out of adjustment, and a visible strip of carpet along the lifted edge stops getting cleaned even though the rest of the pass looks normal.
Part 259221 covers a long-running family of 12 inch commercial Eureka and Sanitaire uprights built on this same base casting: the 1934A, 1950A, 2118B, 2122A, 2124A and 2134A, the C2094B, C2094D, C2094E, C2094F, C2094FB, C2094G, C2094G1, C2094G2, C2094G3, C2094GW, C2094H and C2094H1, the C2095A, the C2132A and C2132B variants, the C2133A, the C2194A and C2194B, the S635A and S645A, and the SC679J, SC684F, SC688, SC689A, SC877D, SC877E, SC886F, SC886G, SC887D, SC887E and SC888G, among a number of related suffix variants sharing this base.
