12PCS Fitting 16MM 4 Types Stable Support Heavy Duty Greenhouse Frame Building Connector Black Suitable for Grape Trellis Sunscreen Shed Gardening

Seem more durable than the joints that came with my greenhouse. I replaced the joints that had cracked since last year because I leave my greenhouse up year round in a windy location. Will update if they fail before a year or two.

Sun damaged the plastic joint pieces in my portable greenhouse. Had to replace a lot of the piping joints because they were old and started breaking. These worked great and I have extras. Great Price.... Thanks.

I bought the 16mm inner diameter black connectors to replace several broken connectors from my greenhouse: enstver L56.5" x W56.5" x H76.5" that I got from Amazon. It was blown over in a rainstorm and broke about 5 connectors.These connectors did fit my model. The only problem I had was that they didn't come with an adapter for the top point of the gable that was broken. I tried using one of the 90 degree connectors, but I had to bend the pipes on the gable to make it work. Maybe in the future they could include a couple of these 120 degree connectors.Other than that, they seem fine and just as sturdy as the original connectors. Just make sure to measure the inner diameter of your original connectors before ordering. I see where several people commented the connectors were too small, but I believe theyordered the 11mm instead of the 16mm.

Greenhouse came with flimsy connectors that snapped when it went rolling across the yard. These things are so much sturdier! (Pool has mystery sprouts in it)

These are not the correct size. They are smaller they do not fit.

Better quality than the ones that came with the greenhouse that broke lol. Fast shipping which I love

Gute Qualität. Alles top.

Connecteurs de 16 mm utilisés pour le montage d'un cadre de bois, support d'une moustiquaire de forme cubique. Montage efficace et même élégant, par contre j'enlève une étoile car la répartition des différentes formes n'est pas pratique, obligeant à transformer un "quatre axes" en un "trois axes".. Bien sur, il s'agit d'un usage détourné, mais si j'avais voulu monter une serre, les difficultés auraient été identiques.

sono veramente robusti perfetti nella misura, un prezzo ottimo.

Bought these after reading reviews, i moved my greenhouse while fencing was being done, forgot to tie it and the strong winds blew it over, when i stood it up the 1 side was limp and i saw a few of the plastics looked fractured, found these, ordered, put the few on i needed to change, they have a far stronger feel to them than the originals that came with the greenhouse, i may end up changing a few more as i go along to have the same connectors on, and know they are more durable.
