C.E. Smith 27648 PVC Post Guide-Ons 60″, I-Beam Frame, White (Pair)

C.E. Smith 27648 60″ White PVC Post Guide-Ons for I-Beam Trailer Frames (Pair)

Loading your boat just got easier. C.E. Smiths 27648 PVC Post Guide-Ons are designed specifically for I-beam trailers and I-beam boat lifts, giving you a clear visual reference for your trailers position even when its submerged during launch. The tall 60″ posts stay visible above the waterline, so you can back down the ramp with confidence and guide your boat onto the trailer without guesswork.

The standout feature is the innovative two-piece mounting clamp, which works above or below the I-beam and fits virtually any height and width of I-beam trailer frame no drilling or frame modification required. The 1-1/2″ square, 16-gauge pre-galvanized steel uprights provide structural rigidity and corrosion resistance, while the 2-3/8″ diameter white PVC posts offer a smooth, low-friction guide surface that wont scratch your hull. Each guide-on adjusts out to 19″ per side, and the pair is sold complete with mounting hardware.

Parts Desk Insights

Best Use Case: These guide-ons are the right choice for boaters with I-beam trailers who struggle to see their trailer frame once its submerged at the ramp a common challenge on steeper or murkier launches. The 60″ post height keeps the guides visible well above the waterline in most ramp conditions, and the universal I-beam clamp eliminates the fitment uncertainty that comes with fixed-bracket guide-ons. Theyre equally useful on I-beam boat lifts where consistent alignment during lowering and retrieval matters. If your trailer uses a square tube or channel frame rather than an I-beam, C.E. Smith offers guide-on models designed for those frame types. Confirm your trailer uses an I-beam frame profile before ordering.
