Connectors

AB-S

No dimple-ribs, stainless steel (70 90 105)

They are suitable for joints in load-bearing wood construction. In the case of increased demands on load capacity, we recommend using the crease. AB angle is suitable as connecting means for the connection with a small load. They are suitable for joints in wood and other materials with nails or screws.
