i have a sick 10 foot long 3 foot high rail. the only problem is i have nothing to top it with. i had like apiece of plastic in top that was like 50 bucks but it shattered. what should i top my rail with? its 4 inches wide.
Go to Home Depot or Lowe's and check out their 2x6 composite decking. Trex Deck is perfect for a rail- slides great, won't break and doesn't chip much.
Join the build-a-jib 101 cult... and you should go with a pvc double barrel. 2 inch pipe, make sure you buy schedule 40. (that's a measure of pipe thickness)
