Extra Long drawer slider

[Jason McK]

I'm thinking of mounting my lights for my new tank on sliders similar to a drawer slider but much bigger.

I've hunted through Goggle with not luck and need a search word.

I know they must make heavy duty sliders that are extra long. But I'm not sure of the application they would be used for so searching for them is a challenge

What I'm looking for is your typical cabinet drawer slider but it needs to hold about 200lbs. and when fully extended have a reach of about 96inches.

Anyone know were I should look?

Thanks
Jason
