In which materials can I use Rampa inserts?

Primarily wood (solid, plywood, particle board, MDF), plastics (ABS, PA, POM, composites), and light metals when the insert with the right geometry is choosen accordingly.

Do you provide drawings or 3D files?

Yes. For most Rampa series (B, SKD, SK, SKL, SKD330, ES, ESK, ESD, BAV, BAN, BAS), 3D models are available on www.traceparts.com.

How strong is the connection (pull-out / shear)?

Highly dependent on the receiving material, drill diameter, embedment depth, and insert type. We have various values for Rampa nuts in wood that are specified in ETA 12/0481. We do have supplier data, but exact values can only be obtained through empirical testing, as they are highly material-dependent and application-specific.

Fields of Application

Typical Uses

Wooden structures such as stairs, balustrades, façades, pergolas, or structural joints.
Fixings that require high load-bearing capacity and minimal edge distances.
Projects where traditional nuts or through-bolts cannot be used.

Installation Guide

Drill the correct hole diameter according to insert size.
Position the insert – the pilot section ensures precise alignment.
Screw in the insert using a hex key – no special tools required.
Check depth and stability, then insert the bolt or threaded rod.

Tip: Always perform a test installation according to your specific wood type.
