Review: Sturdy Frame - Really impressed with how sturdy this frame is. Goes together really easy with 2 people working as a team to assemble it.

## Questions & Answers

**Q: Can this be covered by sheeting or is it designed for a fitted cover?**
A: It is purely for use to cover with any type of covering you see fit...fitted covering would be better as this would prevent wind ingress but some people have used wire mesh to use as a grow frame

**Q: How does the door hold shut? I'd like to use this as a chicken run, but obviously need the door to be secure. Thanks!**
A: I’ve found that the door doesn’t always close properly. But I tie it shut with baling twine, as I only use it for my allotment with netting for my brassicas.

If you’re keeping chickens I would advise using something like a chain and padlock top and bottom of the door for peace of mind.Fox’s can chew through anything that is material based.

**Q: What is the diameter of the poles please? Thank you**
A: If sorry but I don’t know the answer but, it is sturdy once constructed and covered with net for fruit trees.

**Q: how is the cover attached to frame or door?**
A: You put a 3 inch  by 1 inch  frame around the outer frame  one along  the bottom  one 1 metre above then use a 5 metre by 4metre Leno cover over the  top the bottom  is covered  ly netting  for constant air flow

### ⭐⭐⭐⭐⭐ Sturdy Frame
*by A***R on 5 October 2025*

Really impressed with how sturdy this frame is. Goes together really easy with 2 people working as a team to assemble it.

### ⭐⭐⭐⭐⭐ Light weight frame
*by D***C on 13 September 2025*

Easy build with clear instructions. Ive used this as a chicken enclosure, so not sure how it would fare with polythene over it. Would need securing to the ground (not provided) to guard against the wind.

### ⭐⭐⭐⭐⭐ Also makes a great fruit cage !
*by P***N on 20 April 2025*

This is such great value for money and now 10 months on the weather has not affected it at all. Bought this not to be used for a poly tunnel but to cover with netting to use as a fruit cage, looks great and fruit is growing and birds cannot get it. Easy to assemble with one person, 100% recommend this.
