Gripple Dynamic | High-Load Wire Rope Fastener
The Gripple Dynamic (a.k.a. Gripple Lockable Plus) is the high-load member of the Gripple wire rope fastener family. At the same rope diameter it carries more than three times the load of the Lockable: 750 kg along a 4 mm rope and 1,750 kg along a 6 mm rope. The body is ZA2 zinc alloy, the spring is 302 stainless steel and the end caps are UV-stabilised, so the fastener is built for exposed and outdoor runs. Sold as single units.
No MOQ - Buy Exactly What You Need
SOLD AS SINGLE UNITS - order one, or order hundreds.
• No minimum order: the Dynamic is commonly sold in bags or boxes. A job that needs three fasteners should not mean buying ten or more - here you buy the exact count.
• Mix sizes freely: 3, 4, 5 and 6 are all on this page, so one order can cover a run that uses two rope diameters.
• Spares and replacements: a single fastener to finish a run, or to replace one termination, is a normal order here.
• Extra Savings: follow our store and check site banners for our latest exceptional promotions to save on your final order value!
⚠️ IMPORTANT: FASTENER ONLY (Wire Rope Not Included)
This product is the Gripple Dynamic fastener only. Wire ropes shown in illustrations are for demonstration purposes. Perfect if you already have your own wire rope, or need a single replacement fastener.
Why use a Gripple Dynamic?
Choose the Dynamic when the load, not the rope diameter, is the deciding factor. A Lockable Gripple on a 4 mm rope stops at 220 kg along the rope; the Dynamic on the same rope is rated at 750 kg. That can mean staying on a lighter rope and a lighter anchor instead of stepping up a size. Against a crimped or clamped termination, it is made by hand in seconds and needs no swaging tool.
Where is the Gripple Dynamic used?
Heavier suspension drops, catenary wires carrying more than lighting, bracing wires, and outdoor runs where the rope is exposed to weather - work where a standard fastener would be at the edge of its rating. For lighter loads at the same rope diameter, see the Gripple Lockable.
How to use?
-
Pass a length of wire rope through one of the two channels.
-
Loop the rope around the anchor point, or around any suitable bracing point.
-
Return it through the other channel, pulling at least 75 mm (3") of rope through.
-
Pull on the load-bearing section and tension the line. The internal wedges bite harder as the load comes on - this is what carries the load.
-
Lock it by turning the centre button with an Allen key - one turn, both channels. That simple. The lock holds the wedges in place; the wedges still carry the load.
No tool is needed to make the termination; but Gripple Tool for Tensioning can be useful to pull a long span up to tension. Best practice is to fit a thimble at each termination so the rope is not bent around a bare anchor.
🔑 Releasing and re-adjustingA Gripple is one-way by design: rope goes in, rope does not come back. To let the rope run back out
- for dropping a run to its final height, correcting a line pulled too tight, or recovering the fastener for re-use - slacken the centre button first (that releases the extra lock, not the wedges) then use the matching Gripple key to let the rope run back out: the
Flag Key for size 3, or the
Setting Key for sizes 4 - 6.

📢 Technical & Safety Disclaimer
The Safe Working Loads (SWL) listed in the table above are strictly calculated based on a 5:1 safety factor and are only guaranteed when used in combination with original certified Gripple Wire Rope Kits.
Where a size shows a range of wire rope diameters, the stated SWL applies to the largest diameter in that range; thinner rope within the same range will hold less. Sourcing or utilizing non-Gripple, uncertified, or generic steel wires voids these load-holding specifications. The responsibility and liability for system safety and load integrity remain entirely with the user if third-party wire ropes are utilized.
WLL is the load along the axis of the rope. In catenary use the rope tension is higher than the load being carried and rises sharply as sag is reduced, so calculate tension from span and sag rather than reading the load directly from that column.
