The TFH23 is a large sand cast deep ogee cast iron gutter — a substantial profile in the ogee family that combines the characteristic S-curve face of the ogee with a deeper than standard cross-section, giving significantly greater drainage capacity for large roof areas while retaining the decorative ogee character. Available in six sizes from 125×75mm to 255×153mm, the TFH23 range covers a very wide span of building types and drainage requirements.

Suitable for large Victorian and Edwardian buildings, industrial and railway heritage projects, major churches, civic architecture, and any heritage property where a deep ogee profile is either the original specification or the most appropriate heritage choice for the drainage load. Pattern references include No.101, No.101A, No.101B, No.101C, No.101D, and No.28.

The six available sizes make the TFH23 one of the most versatile profiles in the large sand cast range — specify the size that matches your existing installation or that your drainage calculations require. Sand cast iron, manufactured to BS 460:2002. Lead times are typically 8–10 weeks.

Suitable for: Large Victorian buildings, railway heritage, industrial conservation, churches, civic architecture. Call for price: 0333 987 4452.
