We? You mean a professional had you help install the glass? Unlike the huge sheets of glass he installs all day long, the W688 is a dinky piece of glass he should be able to install by himself, using one hand.
All i did was help lower it into position to make sure it was square. Known him for a couple years. Been try'n to get me to work part time. Came from 30-40 minutes away to my home. The $150 was new ppg glass installed.
