Door Closer Product Terminology
Rack & Pinion Applications
Cam Action Applications
Delays the closing cycle to allow slow moving pedestrians to pass through unhindered by the closing of the door.
In-built cushioning during the opening cycle to minimise the risk of personal injury and damage to adjacent walls. This function should not be used as an alternative to a door stop.
Adjustable Latch Action
The speed of closing in the last 10 degrees ( approximately ) can be adjusted to overcome intumescent seals and latches.
All Synergy closers have an adjustment valve which allows the closing speed to be controlled. This is effective throughout the whole closing cycle except when delayed action or latch action are activated.
Slide Arm Application
Can be used where it is not suitable to have a projecting arm. Consists of a single arm connected to a channel mounted above the door. Not suitable for doors with projecting architraves.
Power Adjustment by Template
The closer’s power can be changed by altering the position of the closer on the door in accordance with a template provided.
Power Adjustment by Spring
The closer’s power can be adjusted after the closer is fitted by adjusting the spring tension of the unit to suit door size and site conditions.
