Spiral hooks plastic coated 10 pieces for 6mm | 8mm 10mm expander ropes

Spiral hooks for expander ropes – the secure, durable fastening for tarpaulins, banners & nets

Our plastic-coated spiral hooks are the first choice when expander ropes (including rubber ropes, tensioning ropes and bungee cords) need to be attached quickly, securely and gently. The spiral-shaped hook grips the rope firmly and distributes the tensile forces evenly. As a result, there are no sharp edges or pinch points as with conventional hooks – ideal for durable, reusable connections on tarpaulins, banners, nets, scaffolding protection, tent and pavilion coverings, boat and vehicle covers as well as in warehousing and forwarding operations.

1) Strengths & advantages at a glance

• Secure hold: spiral mount ensures positive fit of the rope – no slipping if the dimensions are correct.
• Gentle on the rope: plastic coating prevents abrasion on the sheath of the expander rope.
• Robust design: metal core for high tensile and continuous load, impact-resistant protective sheath on the outside.
• Quick change: rope can be screwed in and out without special tools – perfect reusability.
• Weatherproof: resistant to moisture, dirt, UV and temperature changes – suitable for indoor & outdoor use.
• Universally combinable: fits standard 6 mm, 8 mm, 10 mm expander ropes and tarpaulin eyelets/nets.
• Clean appearance: matt black look for advertising banners, event construction, trade fairs, sports facilities.

2) Variants & compatibility

The spiral hooks are available in three rope thicknesses. Select the variant that matches the expander rope used:

3) Application & assembly – how the connection works

1. Cut the rope to length: Cut the expander rope to the desired length. Tip: Weld the ends briefly so that the sheath does not fray.
2. Insert the rope: Insert the end of the rope into the spiral holder and turn it clockwise until it is taut.
3. Check position: The sheath should be in contact all the way around; the cable must not be able to be released without force.
4. Mount the opposite side: depending on requirements, mount a second hook, ball, toggle or S-hook – or tie a loop.
5. Load test: carefully increase tension and check fit. If slipping: select the correct hook/rope strength.

Note: Friction may be reduced with wet/icy ropes. In this case, dry briefly or change to the next larger rope strength/hook size.

4) Typical areas of application

• Tarpaulins & covers: Truck/trailer tarpaulins, timber stacks, furniture transportation, garden & camping.
• Advertising technology: Banner rubber tensioners for mesh and PVC banners, construction fence banners, customer stoppers.
• Event & tent construction: Tent rubbers, pavilion covering, trade fair construction, stage technology.
• Sport & leisure: nets, goal covers, boat covers, kayak/roof rack load securing.
• Trade & industry: scaffolding protection nets, dust protection, container/carton fixation in the warehouse.

5) Technical data

6) Material & quality – why spiral hooks are so durable

The load-bearing core of the hook consists of a tough metal wire that can withstand high continuous loads and does not bend excessively even when repeatedly tensioned. The plastic sheathing serves as a buffer between the metal and the sheath fabric of the expander rope. It reduces friction at certain points, prevents chafing and ensures quiet, comfortable handling – a noticeable advantage over bare metal hooks. In combination with good quality expander rope, the service life of the entire system is significantly increased.

7) Practical tips for maximum service life

• Correct dimensions: Hook and rope thickness must match – that’s half the battle for holding power and safety.
• Clean ends: Weld the rope ends briefly (e.g. with a lighter) so that the fabric does not fray.
• No sharp edges: Ensure that tarpaulin eyelets and attachment points are free of burrs.
• UV protection: Store expander ropes in a dry place; direct continuous UV reduces elastomer performance over time.
• Regular visual inspection: sheath damage to the rope or deformation of the hook are reasons for changing.

9) FAQ – Frequently asked questions about spiral hooks for expander ropes

1. which spiral hook size fits my rope?

Select the hook variant to suit the rope diameter: 6 mm, 8 mm or 10 mm. This is the only way to ensure that the rope sits in the spiral mount without play.

2. do spiral hooks hold even in strong winds?

Yes, as long as the rope thickness, hook and attachment point match. For large areas exposed to wind (e.g. mesh banners), use 8-10 mm and use a sufficient number of fastenings.

3. do the hooks damage the expander rope?

The plastic coating reduces abrasion. The prerequisite is an intact rope with a suitable diameter and clean ends.

4. can I use the hooks more than once?

Yes, unscrew the rope, cut it to length again and screw it back in. This makes spiral hooks particularly economical.

5. is there a length limit for the expander rope?

The maximum elongation of commercially available expander ropes is generally approx. 80-100 %. Plan for an elongation of 50-70 % for long-lasting use.

6 Are spiral hooks suitable for continuous outdoor use?

Yes, metal core + plastic cover are weather-resistant. Nevertheless, regular inspection and dry storage are recommended.

7. what is the difference to crocodile/clamping hooks?

Clamping hooks press the rope mechanically – very quickly, but with higher sheath abrasion. Spiral hooks “wrap around” the rope, distributing the load.

8. how many hooks do I need for a banner?

For even tension, we recommend fixing points every 30-50 cm – depending on banner size, material and wind exposure.

9. may I use spiral hooks in cargo transportation?

As tarpaulin/cover holder yes. Expander solutions are generally not permitted for formal load securing (standards for lashing equipment). Use lashing straps here.

10 What to do if the rope slips in the hook?

Check whether the rope and hook thickness match. If necessary, change to the next larger version or twist in the end of the rope again, slightly longer.

11. are the hooks also available in other colors?

Standard is black (inconspicuous, UV-stable). Special colors are available for larger quantities depending on the series – please enquire.

12. can I combine spiral hooks with ball or double hooks?

Yes, a spiral hook is often combined with a second hook or ball end to attach to different attachment points.
