I had a rectangular piece of polycarbon cut to size with 2 holes drilled at each end.The first piece was too short after I took it home to put against the hole in the rangehood to cover the light bulbs & had to get another one cut. This time I gave him 2 hours to do it and he agreed rather than having to go back another day. He did a good job but charged the same as the first piece which cannot be used due to my mistake.
Approximate cost: $25
