Parts
Pontoon connectors — coupling pins, bolts and washers
Floats are not screwed together, they are pinned: HDPE coupling pins engage the lugs of neighbouring floats and are driven home with a mallet. A short pin costs €8.50 net. Double layers and edge finishes have their own versions.

What holds the floats together
A pontoon is not bolted together, it is pinned. The coupling pins pass through the recesses at the corners of the floats and join four floats at each point. The short coupling pin at €8.50 is the normal case, the half pin at €12.75 sits at the edge where only two floats meet, and the long pin at €19.50 joins two stacked layers.
Bolt-and-nut sets secure the assembly along the outer edge, spacer rings compensate for differing build heights. Both are cheap and still easily forgotten: a 2 × 4 m dock takes 19 bolt sets and 7 spacer rings. Everything is included in the complete kits — if you buy individual parts, let the configurator produce the parts list.
Frequently asked questions
As many as there are inner nodes: a 2 × 4 m dock has 21 nodes, of which 5 take short pins and 10 take V-pins. The exact split depends on the shape, because U- and V-floats need their own pins. The configurator produces the full parts list.
Yes. The connection is pinned and bolted, not glued or welded. With a pin spanner and a rubber mallet every coupling pin can be pulled again. That is the real advantage of the system: you can dismantle the dock over winter, rebuild it or extend it later without losing material.
They compensate for the build height between floats of different heights and keep the assembly free of stress. They come in two thicknesses: thick at 38 mm for €3.00 and thin at 19 mm for €2.75. The number follows the length of the dock, not the width — at 4 metres length it is 7 rings.
Only if the other manufacturer uses the same 500 mm grid and the same recess shape. That is not a given — grid dimensions and pin diameters differ between systems. If in doubt, send us a photo of the corner and one measurement and we will tell you before you order whether it fits.
