Bagley Cast Iron Hopper Head No.107

The Bagley No.107 is a deep, confident casting for elevations that need capacity and can carry a little weight at high level.

A stepped moulded cornice caps the head, projecting firmly to throw a strong shadow across the face. Below it the body tapers on all four sides in a long, unbroken sweep to the outlet — a greater depth than most patterns of comparable width, which is where its collecting capacity comes from. The surface is left plain, so the whole effect rests on proportion and on the crispness of the cornice above.

That depth is the practical argument for it. Where a single head takes discharge from a substantial roof area, or from a valley that delivers a sudden volume in heavy rain, the additional freeboard between normal water level and the rim is what prevents overflow down the face of the wall.

It suits Victorian domestic and institutional buildings, chapels, schools, mills and estate architecture — anywhere the original ironwork was substantial rather than decorative.

Cast in solid iron to BS 460:2002, supplied in primer or black as standard, with heritage colours and traditional linseed oil finishes available on request.
