ETA (European Technical Approval)

Would have you thought that RAMPA inserts in hard wood could easily reach more than two tons?

Insert type BL and SKL can achieve pull out strength values of up to 2.250 kg* in spruce. And the best…RAMPA can guarantee this because the inserts type BL and SKL have European Technical Approval.

*in acceptance of ETA 120481 incl. installation guide


The European Technical Approval is a general approved certificate/verification for the technical usability of a construction product in the member states of the EU.

These inserts are used for example in woodwork, stair construction or in shop building for permanent/long-lasting connections.
