Purpose & Fit

This toilet support stop is designed for use with Big John toilet supports in commercial or residential bathrooms. It connects to the existing support structure to provide stable positioning for the fixture. The part is not intended for installations that require a different outer diameter or for use with non-Big John support systems.

Critical Specification

The stop has an outer diameter of 2.5 In and an inner diameter of 1.375 In. These exact dimensions determine whether the component will fit the support tube and mounting hardware. Verify both measurements against the current assembly before ordering to avoid a mismatch.

Material Behaviour

Constructed from aluminium, the stop resists corrosion in damp bathroom environments and maintains its shape under the constant load of a mounted toilet. It does not deform under sustained weight the way plastic alternatives might, ensuring long-term alignment of the support system.

  • Aluminium construction resists corrosion for lasting reliability
  • 5 inch outer diameter fits Big John supports precisely

Questions about this item

What does the 2.5 in OD measurement mean when the stop is installed?

The 2.5 in outside diameter matches the opening on compatible Big John toilet supports so the stop seats flush against the mounting surface.

What connection standard does the 1.375 in ID follow?

The 1.375 in inside diameter fits the standard spud or tailpiece used on Big John toilet supports, creating a direct slip-fit joint.

What clearance is needed to fit the aluminium body?

The aluminium construction requires enough vertical space for the 2.5 in OD flange and 1.375 in ID bore to sit between the toilet support and the bowl inlet.
