- Size 1: The spring coil has an outer diameter of 7.5 mm, an inner diameter of 5.1 mm, the arm is unfolded 55×29×13×13.5 mm, and the wire diameter is 1.2 mm. Suitable for rods up to 4.5mm diameter (coil diameter decreases as envelope flap opens)
- Size 2: The coil is more compact, with an outer diameter of 7 mm, an inner diameter of 4.5 mm, an unfolded 54×29×13×14.5 mm, and a wire diameter of 1.2 mm. Suitable for rods up to 4.0mm diameter (coil diameter decreases when opening envelope cover)
- High-carbon steel wire with surface anti-rust treatment is not easy to deform after repeated opening and closing, and it can return to the position accurately even if there are many letters.
- Easy to install, no modification is required, directly replace the old spring, so that the mailbox door can open and close smoothly, quietly and labor-saving
- Mailbox spring with arm, including 2 sizes, convenient for replacement or whole set upgrade.

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.
