Can anyone suggest a good heavy duty adjustable riser for steel main hatch

[anglooff]

I have been seeking a heavy duty adjustable riser/arm for my main hatch, which is very heavy. The riser preferably will have a minimum 30" extendable arm and have a fully swivel screwable base mounting plate at both ends. (

I have been looking/googling for months without success, as what seems available is specifically geared to small hatches.

can anyone point me in the right direction.

Alternatively a quality dogging system.

As always thanks in anticipation

Regards

See Gas Springs Home Page . Check the applications page. You should be able to find something that works.

Gas springs are what you want. They use them on hatch back cars. The trick is to find the pounds of lift vs the length.

Good idea gentlemen,

I will research what is available.

thanks as always

I had brass hatch adjusters -
like these:
Hatch Adjusters - Brass and Chrome

They worked well on very heavy teak hatches.

I use a teak stick with a notch on both ends. Have several different lengths to vary the opening. Low tech, but I have yet to have one fail.

If you research gas springs get spares as I really doubt the salt will do them well. I use a few on the boat for hatches inside a Corrian dinning table that has storage inside the table. They are like made of 3/4 inch Corrian and are heavy since one is for charts! I replaced a few of the originals but the boat was 17 years old. In a hatch, I'm not so sure they will last that long but it is an off the shelf solution that I know will work. Once you mount them it's easy to replace them. Auto parts stores carry them so if you can find a store with a generous return policy it could be really cheap.

There's info available here and there on the web, but McMaster-Carr carries them in 316 stainless and has a lot of info on sizing them in the first pages of the section on gas springs.
