Your baitcaster needs either 7×4 mm or 8×5 mm – depending on the model.
Search below for your reel or use "Search in page" to find it directly.
Your reel is not on the compatibility list? No worries – just quickly measure the shaft yourself. The crucial factor is the shape/size of the crankshaft (shaft) onto which the handle is mounted. The common sizes are 7×4 mm and 8×5 mm.

Tip: Image shows the difference between 7×4 mm and 8×5 mm.
Quick reminder: You measure the shaft, not the nut – and you need two values at the end: width × height = 7×4 mm or 8×5 mm.
