About This Product
If your toolbox lid keeps falling shut, you need these lift supports.

This value pack gives you two premium struts that fit Knaack StorageMaster 89 job boxes perfectly.

They measure 17 inches from center to center when extended, so you get the right fit and solid hold every time you open the lid.

Installation?
Super simple – just a few minutes with basic tools, and you’re good to go.

No special skills needed.
They’re built tough, designed to last, and take the hassle out of digging through your toolbox.

No more holding the lid up with your head or one hand.
Just pop these on and enjoy the convenience.

And if you’re not 100% sure they fit, just check the OEM numbers on your old ones and drop us a line – we’ll make sure you get the right part.
Great quality, easy setup, and peace of mind – what’s not to like?
