For wide-span roofs, such as those commonly used in hall construction, horizontally running coupling purlins are often used, which rest on roof trusses. To secure the purlins against both tilting and lifting, our cleat SXKN is needed. The extremely load-bearing connector is simply screwed or nailed to the truss and purlin at the crossing points. If this is done in combination with our rafter purlin anchors, the cleats are also excellently suited for wind suction securing. For partial or full nailing you need our SPAX grooved nails or SPAX wood screws.This means for you: very easy installation, no twisting of high timbers such as rafters, coupling purlins, etc.- shear and suction forces are safely absorbed. For certain applications, combinations with e.g. rafter purlin anchors are useful.
