Inward-opening casement hardware

The NP300 set locks an inward-opening side-hung sash from one side while the sash opens both ways from the handle. It suits fabricators who want multi-point locking without the fuller tilt and turn transmission.

Fits these windows

  • Inward-opening side-hung casement sashes
  • Sashes with a single-side multi-point lock that opens both ways from the handle

Profile groove

Set matched to the groove and rebate of your aluminium, thermal-break or PVC profile.

Send the profile section drawing with the groove width and depth, and we match the set to your groove before quoting.

Catalogue part numbers are kept exactly as printed, so an existing order can be matched item by item.

Sizing and load

Load figures below are the ones printed in the AOHUALUN catalogue. A quotation confirms them against your sash, because the glass and the opening decide the real load.

Sash load is the figure the hinge range is rated to in the catalogue. Final confirmation uses your sash width, height and weight with the glass fitted.

Assembly drawing and cutting data

Every order carries the drawing for the profile it is made for, with the fixing points and cut lengths marked on it.

  • The assembly drawing shows the chain from handle through main and side transmission rods to the locking points, so installers can check each position before fixing.
  • Wind bracing is set to the opening you specify; it holds the sash instead of letting it swing.
  • We confirm fixing points and rod lengths against your sash sizes in the drawing set.
