Trying to match a corroded or missing boat-trailer bunk support? C.E. Smith's slotted bolsters and swivel-top mounts may look similar, yet the complete assembled height, individual bracket size and hole pattern are different measurements. Compare the original part number and mounting position before replacing it.

Identify C.E. Smith bunk brackets by number

Part number Bracket type Length Component or hole spacing Slot
10000G Swivel bolster assembly 9 in 8 in bolster 2¾ in
10001G Swivel bolster assembly 11 in 10 in bolster 3¾ in
10002G Swivel bolster assembly 13 in 12 in bolster 4¾ in
10100G40 Double-slot bolster support 8 in Bolster bracket 2¾ in
10102G40 Double-slot bolster support 12 in Bolster bracket 4¾ in
10201G40 Swivel top bracket 3½ in 2 in hole centres —
10205GA Swivel bracket kit 3½ in Bracket with hardware —

Start by separating the complete 10000G / 10001G / 10002G swivel assemblies from the 10100G40 / 10102G40 double-slot supports. The 10201G40 is a smaller swivel-top component, and 10205GA is a swivel bracket kit with hardware. They do not all represent interchangeable complete supports.

Two lengths can describe one assembly. For the 10000G, 10001G and 10002G swivel bolster assemblies, C.E. Smith gives the complete assembled length as 9, 11 and 13 inches, while the bolster components measure 8, 10 and 12 inches. Select by the complete part number and actual mounting geometry, not just one advertised measurement.

Checks to identify the old bracket

  1. Look for any identifying number. Compare the full C.E. Smith MPN. Do not assume G, G40 or GA suffixes identify the same supplied part.
  2. Measure the full assembly. A 10000G uses an 8-inch bolster but measures 9 inches as the complete assembly. The 10001G and 10002G follow the same one-inch overall difference.
  3. Check the slots. The relevant support slots are 2¾, 3¾ or 4¾ inches; measure where the original bolts pass through.
  4. Inspect the swivel top. Compare the mounting hole centres and the original pivot connection, especially when replacing only the upper fitting.
  5. Compare the trailer frame and bunk orientation. Check fastener locations and whether the wood is flat-mounted or uses a separate mounting structure.
  6. Inspect the complete installation. Rust, loose bolts, rotten bunk boards and worn pivots may require more than one replacement part. Use compatible fasteners and follow the trailer manufacturer's instructions.
