These strips were a pain to install because they didn't line up with the roofing corrugations very well and were very prone to splitting without pilot holes. Also, the short 24" pieces were very inconvenient in some areas. What happened to 8' wiggleboard? Does anybody make that anymore? Installation should have been a snap but instead it was tortuous.
This product is only useful as a filled spacer but be careful the lengths do not conform to the waves if put end to end you have to do them one at a time as you install them. They will not accept a screw unless you pre-drill each one because the material is to narrow, all in all a poorly designed product for it's intended use.

Of course, you really need these if you're installing Palruf PVC panels. They work just as they should. Just watch the panels themselves, as they can warp if left somewhere hot. We had several panels sitting in a hot greenhouse and they warped badly.
I used 120 feet and found it to be quite a job to use the wavy closures. They chipped, split and broke on me. They are 3/4" wide, so it is not enough wood to nail or drill into (The old ones were a full 1 1/2" wide). I did not try the plastic wavy closures that Home Depot sells, so I don't know if they would be better. :-(
you must predrill every hole, bought 16 sets=(800 predrilled holes) or it will CRACK in Half and BREAK!
If not perfectly flat when tightened will BREAK! Used under white panels could not see holes when predrilled if you miss by just a 1/4 inch will crack in half. Bought due to price but not worth it , Broke 80% first 3 packages, returned for credit( only good thing about this sale) Spend the extra money and buy the plastic insert if you can fine them
