GLI 30-0410-BLK 4' x 10' Interlocking Safety Fence - Removable Construction Barrier for Temporary Work Sites, Events, and Crowd Control

Not bad at all. Installed on wood deck so it was about a 5 hour install. I had to carefully measure every single hole because I had to miss screw heads, joints between boards, connector plates under the deck, nails holding joists under the deck, etc, etc. Installed 40' of it and ended up running op top of deck boards and making sure every insert was drilled perfectly into the top of a 2x12 joist!!!!! That was tough. Aluminum poles are nice but the plastic inserts are cheap and I doubt they will last, but they did not break. Watch the angle that you drill when taking corners and also remember to slightly reduce your distance between holes on a corner. If this was concrete and you could drill anywhere then this would install in 20 minutes. No way the kids are getting through this. Not bad for $400.
