About this item
- Easy to use: the gear lock is attached by means of the enclosed threaded screws and does not need to be riveted.
- Suitable for windows and balconies: the transmission lock has an adjustment lock, which breaks during the first operation and releases the transmission.
- Attention: the perforated bar can still be used in the gear. If it is worn heavily the gear can no longer hold it properly and move it reliably
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.

I wrote to Bigamart's customer support and they accompanied the process of reshipping the item until it finally arrived. I felt a genuine effort to solve the problem till it was finally solved.

The package was here in Australia from England in a few days — so quick! Something was missing and they refunded it straight away. Pretty happy with these guys.
