I agree with Andy's comments. Buy em if you can.

In 2000 we made our own "roller elevator lift" using extruded sections and home-made rollers. It was 5 sections, and it extended to 3X length using a cable pull of only 1X. It was a mechanical multiplier. It was fast and low-friction (rolling not sliding). But... it was VERY high-maintenance. The biggest problem was keeping the roller axles securely aligned to their extruded pieces. The tiny little fasteners that you like to use with the extruded stock just dont have that much strength and stiffness.

It can be done, but be careful if you make your own. Maybe test it on a fixture - early - to debug.
