How to select the ring diameter?

Most of our clients use a ring with a 45-mm diameter. However, other diameters are available. The following is a 4-step procedure to helpo you determine the right diameter for you.

1) Take a string some 30 cm (12 inches) long, and place it around you’re your scrotum and penis. Remember not to use elastic string, as this would skew the measurements.

2) Make a double knot: the string should be tight enough to make it difficult for you to slip a finger under it, yet not so strong as to cut off the blood flow. Leave the string on for 5 minutes,

3) to make sure it is the right diameter. Cut the string with a pair of scissors, taking care not to hurt yourself while doing so.

4) Measure the length of the string, and consult the following table to learn which is the right diameter for you.

Birdlocked belts offer the following advantages:

With its one-piece manufacturing, Birdlocked offers the advantage of requiring no sheath-ring assembly. The ring is triangular, making it far more ergonomic and better suited to the male anatomy. This in turn makes it very comfortable, allowing it to be worn for extended periods.

Our sheaths’ hand-sculpted designs mean that the resulting product is attractive, with rounded shapes. There are no angles whatsoever, which means the sheaths are very strong, yet aesthetically pleasing. All of our products are shipped in a discrete, moisture-resistant bag.

All of our products re made of surgical silicone. The sheaths offer numerous air holes, allowing the wearer to wash it daily without needing to remove it. Ventilation is also very important: the sheath must allow the skin to breathe, especially if the product is worn regularly. All of our products are packaged in plastic film, which is then sealed to ensure perfect hygiene.

Our silicone sheaths are both flexible and durable. Users may engage in manual labor or sports without any concern about the sheath breaking and wounding them. Its underside locking system (invented by Birdlocked) ensures that the sheath can not be removed without opening the padlock. However, in the event of an emergency, the plastic strip may be cut with a simple pair of scissors without damaging the sheath.
