Choosing Your Greenhouse Hooks
Size and Material Matter
Twist-in hooks suit light tasks (plant ties, small pots up to 2kg), while cropped head bolts handle serious weight – essential when a mature tomato plant reaches 8kg by late summer. Check your glazing bar profile: Elite Greenhouses and Vitavia Greenhouses use 25mm channels that accept standard twist-in designs, whereas older Halls models may need specific screwhook sizes.
Material choice affects longevity. Our UV-stabilized plastic hooks resist degradation from direct sun, maintaining strength for 15+ years versus generic hooks that crack within 3 seasons. Stainless steel options never corrode – worthwhile for coastal locations.
Budgeting & Setup
Budget approx. £14-69 for complete systems. Comprehensive Palram Canopia Trellising Kits include everything needed for 8ft² of vertical growing space.

🔩 Compatibility Guide
Universal Fit vs. Brand-Specific Designs
| Greenhouse Brand | Compatible Hook Type | Channel Width | Installation Method |
|---|---|---|---|
| Elite | Twist-in hooks, Tying eyes | 25mm standard | 90° twist-lock |
| Vitavia | Screwhooks, Cropped bolts | 25mm standard | Thread & secure |

⚠️ Note: Using Elite hooks in a Palram greenhouse may create wobble due to the 9mm narrower channel. Our product pages flag compatibility clearly.
Building Complete Support Systems
1. 3-Step Installation
For Twist-In Hooks:
- Insert: Place the T-shaped head vertically into the glazing bar channel.
- Twist: Rotate 90° clockwise until you feel the resistance lock engagement.
- Test: Apply light pressure (approx 2kg) to ensure stability before hanging baskets.
For Vitavia Screwhooks, simply thread clockwise until the rubber washer compresses against the aluminium.
2. The Training Wire Method
(Professional Technique)
Start with Ring Bolts at 6ft height intervals along the ridge bar. Run 1.5mm galvanized wire between them, tensioned to 20kg pull (no sag). Attach plant ties every 12 inches down to individual plants.
💡 Pro Tip: Position Greenhouse Heaters away from trailing vines using hooks to route power cables safely.
3. Securing Insulation
We recommend Elite Insulation Shading Clips because they feature a 15mm spacer.
This gap separates bubble wrap from the glass, preventing the "condensation cascade" that ruins insulation R-values. Standard clips press material flat against glass, causing moisture pooling. Proper installation improves efficiency for your Greenhouse Insulation.
❓ Frequently Asked Questions
-
Which greenhouse hooks do I need?
For heavy loads (tomatoes/cucumbers up to 10kg), use Crop Head Bolts or metal Screwhooks. For light duties (small pots/tools up to 2kg), use Twist-in Hooks. Our Elite and Vitavia ranges fit 99% of standard aluminium glazing bars made after 1995.
-
Can I use these hooks in wooden greenhouses?
No. These designs are engineered to lock into aluminium channels. Wooden structures require screw-in eye hooks fixed directly into the timber.
-
How much weight can a greenhouse hook hold?
- Plastic Twist-in: Up to 2kg (Baskets, tools).
- Metal Screwhooks: 5-7kg (Medium crops).
- Cropped Head Bolts: 10kg+ (Heavy vines, fully loaded shelving).
-
What is the difference between Alliplugs and standard clips?
Alliplugs create a 15mm air gap between the glass and insulation, which is critical for preventing condensation and retaining heat. Standard clips press insulation against the glass, which significantly reduces thermal efficiency.
-
Are these hooks UV-resistant?
Yes. Our plastic hooks are UV-stabilized to ISO standards to prevent brittleness and usually last 15+ years. Generic alternatives often degrade and snap within 2-3 years of UV exposure.
