All Dam Buster Side and Corner Outlet devices are pre-engineered and sized, and are designed to be used in combination with a correctly sized Dam Buster rainhead so as to achieve compliance.
We do not make custom versions of these products but many are adjustable on site for varying applications - please refer to our Product Technical Statement for specific information about what is possible.
So long as the overflow device and a Dam Buster Rainhead (in combination with correct downpipe sizing) is selected in accordance with the total design flow rate in the box gutter/s from the Dam Buster rainhead design table, the Dam Buster overflow device automatically has sufficient hydraulic capacity for any allowable combination of flow rates.
They might look simple but all of these devices are complex, fully engineered, tested and certified products which fully comply with the conformance and compliance requirements of the National Construction Code. This means they can be selected and certified with absolute confidence in all areas of Australia.

Side, End, Corner and Crucifix Outlets Solve An Age Old Drama
Dam Busters side, end, corner and crucifix devices use the power of gravity to easily and safely change the direction of water flow in box gutters, then take it to the point of discharge fitted with a Dam Buster rainhead.
All of these amazing devices also feature inbuilt adjustability to make installation a breeze e.g the TSO-300 ("T" Side Outlet) expands on site and without additional tools to custom fit any incoming box gutter between 300 and 450mm wide. See pages 50-53 of our Product Technical Statement HERE for more information.
Product dimensions can be found HERE.
Like all Dam Buster products, these amazing devices will suit virtually any installation, new or retrofit and have already revolutionized both innovative design plus rectification of existing problematic (non-compliant/defective) installations.
"L" shape - 'End Side Outlet (ESO), with one box gutter only discharging to the device. This device sits at the end of a box gutter and used to change its direction 90 degrees into another box gutter. It requires no sump or additional pipe work or bulkhead to install. Available ‘left’ (L) or ‘right’ (R) handed* SKU ESO-XOO-L or R (where XOO is the box gutter size in mm e.g ESO-400-L).
"T" shape - 'T' Side Outlet (TSO), with two box gutters discharging to the device and then to a single outlet point. Requires no sump or additional pipe work or bulkhead to install. Very useful for 90 degree side outlets from box gutters. SKU TSO-XOO e.g TSO-200
"T" shape - Corner Side Outlet (CSO). This enables two box gutters at the corner of a building to discharge to a single rainhead (for example, on a Hip roof) SKU CSO-XOO-L or R e.g CSO-300-R. Also requires no sump or additional pipe work or bulkhead to install.
"X" shape - Cruciform Side Outlet (XSO). Accepts three box gutters discharging to a single outlet device (for example, where the device is located at the party walls in a row of terrace style houses, having hip ended roofs at the front or rear parapet wall) SKU XSO-XOO e.g XSO-300. Also requires no sump or additional pipe work or bulkhead to install.
* To determine LEFT or RIGHT for ESO and CSO devices, just imagine you are in a small boat travelling down the box gutter with the flow and wanting to turn LEFT or RIGHT at the device.
Used in series or in combination, virtually any box gutter directional discharge problem can be easily solved, even in a retrofit situation, by using these revolutionary Dam Buster products.
NOTE: Requirements vary from state to state, however a Performance Solution is likely to be required for installation certification purposes of these Dam Buster devices; that document should be developed by a suitable expert such as a qualified hydraulic engineer, in accordance with the requirements of the National Construction Code.
