Railblaza Hatch Wedge PairGaps of 25, 50, 75, and 125mm (1, 2, 3 and 5") are achievable simply by changing orientation, and it can be easily tethered.
Suitable for most hatches including Lewmar, Goiot, Moonlight, Vetus, Bomar, Gebo and Maxwell.
Being regular boaties, we got frustrated with the friction hinges not holding our hatches up. After many attempts at finding the perfect object to hold the hatch at different heights, the idea of a multi position hatch wedge was born. Simple, but effective, the pattern of ridges and recesses will stop it from slipping out of most brands of hatch when in place, and it will hold the hatch open at 4 different height settings. |
