Re: Product Code- 10-129

My house was built in 1977 and has the original vintage looking swing-out frosted glass shower stall door. This morning, the aluminum handles fell off. They are 6" long, however the pre-drilled holes are 3 1/2" apart on the door. I'm looking for information about how this item is installed before purchasing. How do they attach, in other words? The door is framed and is standard thickness. Thanks!

The 3 1/2" holes should be all the way through the door. That way, the male and female handles can be screwed together.
