Frequently Asked Questions

How many products do you actually make?

Four product families covering thirty published classes between them. That is the complete range, there is no separate catalogue held back.

Which family should I look at first?

Start from the site environment. Clean air points at standard type, salt fog and industrial pollution at fog type, dry sand and dust at aerodynamic type. Then pick the strength class from the load case.

Do all four families use the same couplings?

They overlap. 16 mm covers the common 70 kN to 120 kN classes across all three profiles. Above that, standard type continues through 20, 24, 28 and 32 mm couplings.

Are prices listed on this site?

No. Price depends on class, quantity, marking and packing, so it is quoted against a specific enquiry rather than published.

Not Sure Which Class Your Specification Means

Send the designation exactly as written, with the coupling size stamped on the units you are replacing. Those two identify one column in one of our tables.
