Description
Overview:
The Monument 308L Waste Nut Box Spanner is a dual-size tubular spanner for fitting and removing waste back nuts on sinks, basins, and baths. Made from robust steel with a precision-formed hex at each end, it provides a secure grip on common waste fittings while allowing access in tight, recessed spaces. One end is 46 mm (1.81 in) and the other is 50 mm (1.97 in), covering two popular sizes in domestic and commercial plumbing. Holes through the tube let you insert a tommy bar for extra leverage and control. Designed for both professional plumbers and DIY users, the 308L helps prevent rounded fasteners and speeds up installation and maintenance work. Brand: Monument. Model: 308L. MPN: MON308.

- Cross-holes for a tommy bar provide increased torque and better control in confined spaces
- Strong steel construction for durability and consistent performance on site or at home
- Precision-engineered faces help reduce slip and rounding for a cleaner, safer fit
- Compact form factor for easy access under basins, baths, and kitchen sinks
- Suitable for installing, tightening, and removing waste fittings in new installs, repairs, and maintenance

Typical Applications:
Ideal for loosening and tightening waste back nuts on bathroom basins, kitchen sinks, and baths, especially where space is limited behind pedestals, bowls, or cabinetry. Useful during first fix and second fix plumbing, trap and waste changes, seal replacements, and general maintenance where a standard open-ended spanner cannot reach.
