(Available January 2015)
This is the latest model connector for stair assembly and in particular the upstairs angle joint. Using a key hole shape in a metal disc which is fitted into the post and a bent angled shaft with a head to engage the disc so it is an easy connection. The connector relies on the Zipbolt gear housing to tighten and close the joint with not many turns needed, it is best done with a side ratchet tool using it with a 5mm hex bit. This product will be available in a single pack with instructions in a poly bag as well as in a twin blister pack containing a driver and 2 wood plugs.
The approach we recommend in fastening the rail will be to use the 11.550 Angled Railbolt in the downstairs joint which will be self supporting of the rail and then use the Angled Slipfix Railbolt in the upstairs joint.
