Here are three types of bottom plates offered by Alumi-Span:
- Standard Bottom Plates: The standard bottom plate is great for solid, sandy lake bottoms on docks over thirty feet long. This 6”x6” plate fits around both a 2” OD pole or a 1.9” pole. The advantage to using bottom plates is you can leave your entire leg set together when taking the dock out each year.This not only makes installation easier, but it also minimizes levelling of the dock from year to year. These plates can also be moved up the pole a bit for milder muck situations.
- Large Bottom Plates: The large bottom plate provides added support and is used for a variety of reasons. These 12”x12” plates are ideal for supporting party platforms. They not only add stability, but they make installation of a platform easier as well. This is because they allow the truss to stand on its own in the water as sections are added to it. These larger plates are also helpful when muck is an issue (up to a foot and a half of muck). The plate can be run up the pole, so that the leg set can be jammed into the muck and still have something stable on which to rest.
- Bottom Plates and Treated Boards: For more extreme muck conditions (over a foot and a half), a treated piece of plywood with a hole in the middle can be used in combination with a standard bottom plate. The upright poles of the leg set go through the board, while the bottom plate rests on top of it. The board creates a stable surface on which your dock can rest. It also gives you something to stand on while doing the install.
