Optiparts Mast Step, round cup without locking system

Manufacturer part #: EX1202

Mast Step Cup Style: Stainless Steel adjustable mast step with engraved adjustment scale in base plate. Different mast rakes can easily be repeated using this scale. The cup is oval shaped allowing the mast to move fore and aft giving the best upwind and downwind performance.

Side to side movement is restricted. The slide plate is so manufactured to limit up and down movement. Best held to floor with a flathead 5 mm screw.

No. 10 screw will also work. This mast step has a base plate with a double upright captive screw support. Earlier models had one up right that was slotted. While the cups for both models are interchangable the nuts are not.

When compared to the pin style mast step this mast step is more reliable in terms of breakdown free performance.
