Step 1
Before assembly, test each Silicone C-ring about 1 inch behind the glans to find the best fit. It should be snug but not restrict blood flow. If using the silicone comfort sleeve, put it on first, then apply the C-ring.
Step 2
Fold each cord evenly in half, and then insert the loops 2"-3" into the side holes of a desired c-ring. Then thread the cord ends through the loops. Position the cords facing downwards as shown in the photo.
IMPORTANT: Never open the silicone c-ring by the "side handles." These side handles are for the cord loops only. The proper way to open is by pulling the middle hole apart with your index fingers to slide on 1" behind the penis glans and off.
Step 3
Thread the first set of cord ends down through the D-ring of the knee strap with the logo tag pointing upward.
D-Ring
Step 4
Insert the cord ends into the cord lock to extend 3"- 4" out from the round end. Push a wheel with a coin (or another hard object) into the round end of the lock until you hear a "click" sound. This indicates that the wheel is secured in place. Repeat the same with the other set.
Step 5
Buckle the knee strap above or below either knee cap with the logo tab facing upward on the inside of the leg. Stretch open the CENTER hole of the silicone, and place 1" behind the penis head. Now you can adjust the tension of the cords to stretch the penis. Switch legs daily for different angles to stretch.

Step 6
Pull the cords with one hand while pulling the cord locks in the opposite direction with another hand to lock in the desired tension. Keep the tension in place by tying cord knots (circled in the photo).
The cord ends can be tucked away behind the neoprene of the knee strap for extra comfort and to be more discrete.
Step 7
The shorter the cord length between the silicone and the wheel locks, the higher the tension. Adjust for comfort and tension to extend your stretching session.

Quick Start Instructions
Not shown in the video yet after assembly:
Put the silicone sleeve on like a condom, then open only the C-ring middle hole—never the side holes. Sleeves are available on our shop page or Amazon if you don’t have a 2025 set.

IMPORTANY:
ALWAYS OPEN SILICONES FROM THE CENTER HOLE
EASY. DISCRETE. EFFECTIVE.
PARTS
Knee Strap |
The knee strap is neoprene cushioned, hypoallergenic and latex free. It should be worn above or below the knee with the D-ring pointing up on the inside of either leg. Below allows more tension. Above is more comfortable and you don't need to adjust the tension as much when sitting/standing. Switch legs daily for a good stretch at different angles.

Power Cords & Cord Locks |
The cords are latex-free. The cord locks will allow you to select a desired tension.
ACCESSORY
%20(.png)
Self-Adhesive Wrap |
It helps to increase comfort and grip. Lightly wrap a few times to several times behind and around the glans before placing the silicone behind it on the penile shaft.
DOUBLE/TRIPLE STACK METHOD |
It helps to increase comfort and grip. Lightly wrap a few times to several times behind and around the glans before placing the silicone behind it on the penile shaft.
NON-SLIP
Prevent Slippage for Maximum Grip |
PRO TIPS
Bent Silicone
Tension Cord loops placed to the sides of the c-ring side holes
Silicone Straightened
Tension Cord loops placed at the bottom of the c-ring side holes facing your feet
Silicone Care
Wash silicones after every use with warm soapy water.

Warming Up Before Stretching
The penis should have a good amount of blood flowing prior to penis stretching. It could be achieved by taking a hot shower/bath, massaging with warm hands, and/or wrapping a warm cloth around the shaft. Tip: If the penis is retracted before use, you can gently stimulate your flaccid penis to get longer by taking your index and middle finger and pushing it into the sides of the base of the shaft into the pubic region, and then gently shake the penis to stimulate it. Tip: If your flaccid penis is still retracted, achieve an erection (no lube) and put the wrap behind the glans several times, and put on the entire system when erect, and then once the erection goes down you can start stretching.

Putting on/Removing The Sleeve & C-ring
Putting On Silicone Comfort Sleeve: Open the sleeve with your index and middle fingers, and place it behind the glans, down the shaft.
Putting On C-ring: Use your thumb and index fingers with both of your hands to carefully pull open the CENTER HOLE of the silicone C-ring, and place it 1" behind the glans on the shaft or sleeve.
Never open the silicone by the side handles. The sides are for the cord loops only.
​
Removing Use soap on the shaft to slide off the silicone.
Double & Triple Stack for the most grip
After positioning the assembled silicone C-ring about 1 inch behind the glans on the soft/flaccid shaft, you can add one or two additional unassembled C-rings in front if you need more grip.
Baby Powder (if needed)
Whether you’re using one to three C-rings, you can apply baby powder to the shaft before placing a C-ring on, or after the sleeve is in place.

INITIAL Length of time to wear
Beginners 10-20 minutes each stretching session to start the first two weeks 3 times 5-7days a week. Take 5-10 minute breaks if you will continue stretching after a session or space them out. Gradually go up in the coming weeks as your penis will get used to the tension and stretching in general.
Experts Can wear daily for several hours at a time. We recommend 5-10 minute breaks and continue stretching. If you want to take 1-2 days off a week (not together) you can do this and not affect gains.
Post-Stretch Use (Anti-Turtling Sleeve):
After your stretching session, you may wear the sleeve to help maintain length and prevent retraction (“turtling”). This keeps the tissue gently extended as it recovers. Wait a few minutes after stretching to restore normal circulation, then slide the sleeve on. Wear it for 1 to 3 hours, or as long as it feels comfortable and secure. The fit should be snug but never tight. Remove immediately if you feel numbness, coldness, or
discoloration.

Circulation & Discoloration
The silicone should fit snugly and not cause any pain to your shaft skin or head/glans. Slight skin discoloration is normal and usually goes away within minutes. Remove immediately if signs of overuse appear. i.e., Skin turning dark purple/black, head feeling cold or tingling sensations.
Recommendation Consider a larger-sized silicone with additional wrap behind and around the glans to create a good-sized ridge. This way the larger silicone will be comfortable with no slippage.

Do NOT wear while sleeping
The penis can not be monitored when you are sleeping and you might roll around.

Cure the cord ends
Under normal use, the cord ends may need to be cut 1/4" and cured by a lighter to make it easier to pass through the cord locks.
