Gripple Dynamic

Gripple Dynamic | High-Load Wire Rope Fastener

The Gripple Dynamic 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 three hundred.

• No minimum order: the Dynamic is commonly sold in packs of ten. A job that needs three fasteners should not mean buying ten - here you buy the exact count.
• Mix sizes freely: 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.
• Dynamic Savings: follow our store and check site banners for our latest 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?

1. Pass a length of wire rope through one of the two channels.
2. Loop the rope around the anchor point, or around any suitable bracing point.
3. Return it through the other channel, pulling at least 75 mm (3") of rope through.
4. 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.

No tool is needed to make the termination; a tensioning tool is only needed 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.

Sizes and working loads

Size	Wire Rope Diameter	WLL - along the rope	SWL 5:1 - vertical suspension
4	4 - 4.75 mm*	750 kg	150 kg
5	4 - 5 mm	750 kg**	150 kg**
6	5 - 6 mm	1,750 kg	350 kg

* 4.75 mm only with Gripple wire rope. ** No separate manufacturer rating is published for size 5; it is listed at the size 4 rating, the lower and safer figure.

📢 Technical & Safety Disclaimer:
The Safe Working Loads (SWL) listed in the table above are calculated on a 1:5 safety factor and are only guaranteed when used in combination with original certified Gripple wire rope. Using non-Gripple, uncertified or generic steel wire voids these load-holding specifications, and responsibility for system safety and load integrity remains entirely with the user. 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.
