White and black PVC guide-on posts can look similar when removed from a boat trailer. C.E. Smith 27620 and 27626 are 40-inch sets, while 27640 is a taller 60-inch set. The distinction affects the steel upright, sleeve length and lateral adjustment, not just the PVC colour.

Identify the post kit

All three models are sold as pairs with mounting hardware and fit standard trailer frames up to 3 inches wide by 4-1/4 inches high. The PVC tubes have a 2-3/8-inch actual outside diameter.

MPN Assembled height Post colour Adjustment per side PVC sleeve Steel upright
27620 40 in White PVC 13 in per side 31-1/2-in white PVC sleeve 18-in vertical steel upright
27626 40 in Black PVC 13 in per side 31-1/2-in black PVC sleeve 18-in vertical steel upright
27640 60 in White PVC 19 in per side 47-1/2-in white PVC sleeve 39-in vertical steel upright
Post height means inches. The 40-inch and 60-inch model names describe height above the trailer frame, not a length in feet. These are unlighted post guide-on kits; trailer lights remain a separate requirement.

What to check on the original trailer

  • Waterline and height: 40-inch sets are lower; the 27640 stands 60 inches above the frame.
  • Frame crossmember: compare its width and height with the 3-inch by 4-1/4-inch standard mounting limit. A longer U-bolt kit is a separate solution for some larger frames, not part of the standard kit.
  • Adjustment range: the 40-inch sets adjust outward to 13 inches per side; the 60-inch version adjusts to 19 inches per side.
  • Position: the posts should be near the rear of the trailer, while still allowing the widest part of the boat to pass through them.
  • Replacement parts: 27620 uses white sleeve 11339; 27626 uses black sleeve 11329; 27640 uses white sleeve 11340. Uprights differ between the 40-inch and 60-inch versions.
