This is seriously helping me clear some space on my desk, between work and gaming - I always stack my stuff. Was able to hang this within an hour to 1.5 hours, opted to drill in holes to support the added weight. Instructions were OK, felt the drill holes guide page wasn’t needed and opted to do the following:1) Recommend using a level to line things up well & just peel off the adhesive and place all pegboards where you want them.2) Once that is done, remove all the boards and leave the adhesive plastic backing on the wall (it’s an upwards lifting motion)3) Drill a small hole through all the drill holes/and straight through the plastic adhesive4) Remove all the plastic adhesive backs and drill the holes larger if needed5) Add drywall anchors, place the adhesive backings back lining up drill holes with the drywall anchors and screw everything down6) Re-add pegboards to the plastic backings (downwards motion to lock it in)This made it a lot easier to do every step for all boards at once vs. hanging 1 board at a time - good luck!
