  • Perfect for pontoon change room
Style: 20 inch Pattern Name: 40 Lbs/178N
Easy installation and just the right amount of resistance for the change room hatch.

  • Great Product and works great!
Style: 20 inch Pattern Name: 40 Lbs/178N
Installed with no problems and hope they last as long or longer the the original ones did.

  • I'll tell you in about 5 years if they survive.
Style: 15 inch Pattern Name: 22.5 Lbs/100 N
They arrived PDQ, thanks to all involved in that process. But and that's a BIG BUT - How can you actually rate a product if you can't consider how it performs over time. Something of this nature should exceed the five (5) "year" mark, yet I am asked for a review 5 "minutes" after I installed them. Does anyone else find this absurd, or am I the only one? Are they doing the job right now, yes - and for that they got the three star placement. If I'm not pushing up daisies in five years I'll try to remember to let you know if they still are - as they should be. (Or are not.) Have A Great Day Ya' All ... show more

  • Very strong lifting capacity.
Style: 20 inch Pattern Name: 180 Lbs/800 N
After putting on my truck bed cover that is made of fiberglass it takes a little effort to close but pops the cover right up. The strong lift and hold capacity make it safe to be under the cover while raised in windy conditions as it won't budge. Very satisfied.

  • Replacement units, easy to install, instructions clear.
Style: 20 inch Pattern Name: 40 Lbs/178N
