FA102 / HD102 Latch

• For large top hung vents the friction arm can be used as an extra support by fitting it below the existing friction stay.
• It has the effect of limiting the opening as well as adding greater stability to the window.
• The FA102 / HD102 latch mechanism is released using a suitable spanner allowing the vent to rotate to its full opening potential, facillitating the cleaning of the exterior glass from inside the property, before being re-engaged to retain the restricted opening.
• To release the FA102 / HD102 latch, use a suitable spanner, rotate the latch upwards by 90 degrees and lift the restrictor arm over the retaining rivet.
• To re-engage the FA102 / HD102 latch, replace the restrictor arm over the retaining rivet, rotate the latch back 90 degrees and ensure the latch securely engages the retaining rivet.
