Pryda has developed a new 90mm cyclonic grip in its latest battle against cyclones.
The grip is used in high wind regions for tying roof trusses to wall frames and has been added to the Pryda range to suit the increasingly popular 90mm steel frame.
The new 90mm cyclonic grip complements Pryda’s high capacity tie down product range. The product category includes tie down plates, grips and overstraps that provide uplift capacity up to 100kN. The existing cyclonic grip is 58mm wide and has been specifically developed for steel frames with a stiffened top plate.
On their own, the Pryda cyclonic grip can achieve tie down capacities up to 14kN – but when doubled up with an overstrap, tying down a timber truss on a stiffened steel top plates achieves up to 38kN capacity.
The 90mm cyclonic grip can be fixed into steel top plates using M6x22mm GX screws or 10 gauge x 16mm Teks screws. If the grip is fixed to timber top plates, 12 gauge x 35mm type 17 screws need to be used.
The Product Update section of the Pryda website www.pryda.com.au contains all design data for the complete cyclonic grip range.
