两个圆角的方块下面应该有螺丝或空心铆钉。
用刀或电笔翘开看下。
空心铆钉的话用电钻打孔的方法去掉。
【装修】求教 HDB窗户把手坏了怎么换?
There are 2 types of handle latch , one screw on each side and 2 screws on each side , you take out the existing
one ( remove rectangle cover) and bring to hardware shop to get the same hole position type ( you no need to drill
hole again ) , the left hand side plate not easy to buy , after fixed the RHS latch , try to close , if the old LHS plastic plate
block the closing , you either 1. remove the LHS plate or 2. remove or file /cut the plastic tip on new RHS latch.
1 screw on each side of the latch type is cheaper as some one saying $3 each and the 2 screws on each side type its more
expensive , if your quantity is only one , it is not worth to search for whole seller to buy at $2-3 each , just get from your
neighborhood hard wear shop will do. Happy DIY
