I made these wood brackets out of 3/4" MDO Plywood scrap pieces to hold a 2" Round PVC Pipe, attached them to our 4ft x 8ft weeding table with cutting mat and it works great.
Been using it for over 15yrs now.... The PVC Pipe Caps hold the pipe in place on between the wood brackets when you pull on the application tape.
It holds up to 48" wide rolls of application tape. You can pull the application tape the full length of the 4x8 table and it stays above the vinyl to be masked. Your squeegee press the tape
to the vinyl as you go without wrinkles. One person can apply 48" wide rolls but it helps if 2 people are both squeeging from both sides of the table. Works great. Only problem I've had is if the vinyl has been rolled up and is wavy and not laying flat.....
