Clear

The RB501COG is a side rafter rise and fall bracket for the common ogee cast iron gutter. Where there is no fascia board — on open eaves, or where the rafter face is the only available fixing point — the RB501COG mounts directly to the side face of the rafter and provides adjustable support at the correct height for the common OG gutter run. The bracket cup is shaped for the ogee S-curve profile.

The threaded rise and fall cup allows precise fall setting at each bracket position independently of the rafter pitch, eliminating shimming and packing on long runs or where the roof line is uneven. Available in three sizes to suit the standard common ogee range: 100mm (4″), 115mm (4.5″), and 125mm (5″).

Also compatible with common ogee guttering manufactured by Osma, Marley, Hunter, and Lindab, making it a practical bracket solution on mixed or partial replacement installations. Specified on listed buildings, heritage conservation projects, and period properties across England and Wales where the common ogee is the correct profile.

Compatibility: Common ogee gutter 100mm, 115mm, 125mm. Also suits Osma, Marley, Hunter, and Lindab common OG. For specification support, call 0333 987 4452.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

My builder has calculated out our heating requirement in each room of our house in BTU’s. Can you tell me what BTU’s stand for, and is this different to KW.

BTU stand’s for British Thermal Units. This was the old (Imperial) measurement for heat in connection with plumbing. Although BTU’s is a term still commonly used within the heating and plumbing, the industry is now going over to KW’s Kilowatts.

What is the advantage of a louvre-face airbrick over a square-grid pattern?

What is the advantage of a louvre-face airbrick over a square-grid pattern?

The louvre face provides directional airflow and offers some resistance to driven rain entering the subfloor void, making it a practical choice for exposed elevations or properties in areas with significant prevailing wind and rainfall. The square-grid (school board) pattern offers a larger open ventilation area but less weather protection.

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

My house has a plastic guttering system. Can I use your brackets to replace my exisiting broken ones?

Our brackets are more commonly used on cast iron rainwater systems. Unlike plastic, cast iron is heavy and the weight keeps the gutter in position. As such our brackets do not normally have retaining clips which could lead to plastic or lightweight gutters blowing out of the bracket. The profile of your gutter should match that of our bracket but without the weight to keep it in place you may well encounter problems in bad weather.
