Are angled supports necessary for pvc rails?

[SlickRick.]

im building a 10 ft long pvc rail. it has a 5 inch sliding surface, it is supprted by 5 evenly spaced columns of two 1.5' tall 2x4s , and under each column is a 4' long 2x4 so that it doesnt tip. does this sound sturdy enough, or should i angle a 2x4 from the tip of each base 2x4, to the sliding surface. ive seen pictures of pvc rails with, and without these angled supports, but idk if the rail will last without them.

yeah i would say so i once made one without them and with in a week it was so woddly i have all mine with angled things now and it is so much more sturdier

Short answer, yes.
Long answer, yeah you should because all it will do is make your rail sturdier. Sturdier = safer = less injuries right before ski season. It's doesnt take much more work/effort and will make the rail ALOT sturdier. Just do it.

if you want your rail to be soild, its worth it. but if your cheap than you could pobley get by with out them for awhile depending on how you attached the legs to the feet. but in the long run its probley worth it. you could also rip the 2x4s in half and get twice as many board feet, that way you can save a bunch of wood by using you newly created 2x2's for the supports
