Frequently asked

Heavy duty anchor or throughbolt?

The heavy duty anchor's three-part expansion sleeve spreads load further than a throughbolt's wedge, and the range runs to M24 for more demanding duties. The ranges overlap and both carry Option 1 assessment - pick by the duty and the specified anchor type, or send us the fixing schedule.

Can you supply the certificates?

Yes - ETA documentation for the range is available on request. Send us your requirement and we will quote within 24 hours.
