Understand automatic hardware selection
What this does
Explains how the system chooses handles, hinges, locks and rollers for you: rules match each sash against its type, size and weight, so the right set is on the order without anybody looking it up.
How the selection works
-
01
The analysis measures every sash — its type, its dimensions, its weight with the specified glass.
-
02
The brand and series in the design narrow the hardware that may be used.
-
03
The rules for that series are evaluated against each sash.
-
04
The matching set is added to the line, and appears in the analysis as Hardware Sets (pcs).
What the rules key on
- Sash type — casement, sliding, tilt-and-turn, folding. A criterion, not a separate catalogue.
- Size and weight — the reason a heavier glass build-up changes the hinge set without anyone editing the hardware.
- Handing — left or right, where the set differs by hand.
Example
Two sashes on the same elevation get different sets: the 700 mm casement takes the standard hinge, and the 1200 mm one beside it — the same series, the same glass — takes the heavy-duty set, because its weight crosses the threshold in the rule.
When it picks nothing
An empty hardware result almost always means the rules have a gap, not that the sash needs no hardware. Check that the series has a ruleset, and that the sash's size and weight fall inside a rule's range. Tell whoever maintains the hardware data — a gap silently under-costs every future quotation that hits it.
Common mistakes
- Adding hardware by hand on the order line, so the next analysis overwrites it.
- Assuming the set is wrong when the glass specification is what changed.
- Shipping a job whose analysis shows no hardware — the store cannot issue what was never listed.
