MQ200 series
Top-hung (awning) vents set into curtain wall framing: opened by a pegstay, held by two friction stays, and locked by a plate at each end of the vent.
Adaptation
Check the window type and the profile groove before choosing codes. If your profile differs, send the section drawing and we will confirm the set.
Hardware set
Codes are the ones printed in the AOHUALUN catalogue, so an existing order can be matched line by line. Quantities are per window or per leaf unless noted.

Dimensions and load

Installation and cutting
The information below is what the window maker needs before cutting rods or drilling the profile.

We confirm the groove position, handing and locking points before the set ships. Add the catalogue codes you already use, and we will check them against the current set.
