We use our Vertical SelfClose mechanism in a duct channel & lid, as shown on our downloadable data sheet. This system will operate slide panels up to 1500 x 2200, single glazed, weighing up to 60kg without too many problems, providing the 30/09/07 slide panel advisory is followed, usually attached to every quotation.
2. Architectural Joinery (from 35 to 40mm edge)
We use our Horizontal SelfClose mechanism, which is fitted into the slide panel top rail, as shown in project photo's usually attached to every quotation.
This system will operate larger slide panels and/or, double glazed panels, weighing up to 100kg. However, we can advise the maximum successful "practical weight" slide panel self-closed, has been weighed at 140kg.
Note: Practical Weight: Be aware, the NZ standard (NZS8500-2006) requires the door (or slide panel) to selfclose from the 150mm 'Open' position.
Therefore, to move the slide panel to this 'Open' position, the user has to overcome first, the weight of the panel plus, the spring pressure required to close it from 150mm 'open'. Therefore, the wider the panel is opened, the harder the panel is to move, as the springs become progressively fully extended.
It would be appreciated, at some stage, the combined slide panel weight and panel drag (resistance) plus the spring weight required to move the panel, will make the panel impractical to open or operate, by the end-user.
The Aluminium Fabricators challenge: To maximise the size of the slide panel while taking steps to reduce panel inertia (drag) caused by both;
- Carriage wheel/track deflection, caused by the glazed weight of the panel.
- The weather seal brush drag, caused during door operation by excessive
Meanwhile, Swish systems have been approved under the "Exemption Schedule" of the Fencing of Swimming Pools Act 1987 and now, with Territorial Authority acceptance of the NZ standard (NZS 8500-2006) soon to be incorporated into the Act
- Swish take the opportunity to again confirm, all Swish Pool Access Safety Systems have been designed to provide for two levels of safety in operation, as required by the standard and defined under clauses 2.3, 3.7 and 4.6.
