GRB 103

Experience a masterclass in deep-set fluid containment and heavy-gauge internal fulfillment with the GRB 103. Specially engineered as a shorter, highly manageable modification of our classic CT-103 colon tube, this advanced 12-inch silicone nozzle is designed with a robust 1.3-inch shaft diameter. The standout feature of this model is its, retention ball positioned strategically just ahead of the final safety flange. This innovative modification provides a secure solution that anchors the nozzle effortlessly after full insertion up to the flange, letting you administer enema solutions with stable confidence. Shared from our classic rib-style CT-103 colon tube, the segmented tip design allows the nozzle to naturally adapt and traverse the lower anatomy smoothly.

Heavy-Gauge Shaft Geometry & Monumental Threshold Lock: The architectural layout of the GRB 103 provides a massive mechanical advantage by offering an unyielding fluid-retention barrier right at the threshold. It features a robust, consistent 1.3-inch main shaft diameter layered with a segmented, ribbed tip section that enhances internal stimulation while providing the flexibility needed to track internal curves smoothly. As the tube moves into position, the tip places solution deep into the lower sigmoid colon, promoting a smoother, more comfortable filling experience while actively helping to eliminate early abdominal cramping. Right at the base, the profile swells into a prominent, enlarged 2.0-inch diameter retention ball before settling into a 1.0-inch long, 1.3-inch diameter retention valley. Your pelvic floor muscles contract naturally over this groove, locking the tube hands-free against a stable, flared safety base.

Anatomical Design & Dimensions:

• Total Length: A balanced and highly stable 12.0” overall length from tip to tail.

• Maximum Insertable Depth: Provides a deep-reaching 11.0” of fully usable insertion length to access deep internal contours.

• Deep Sigmoid Comfort Reach: Delivers fluid directly into the lower sigmoid colon, ensuring a deeper fill that minimizes early muscle contraction and cramping.

• Robust Ribbed Shaft: Features a heavy-duty 1.3” main shaft diameter with a segmented, ribbed head section for optimal internal flexibility and guiding alignment.

• Prominent Retention Ball: Rises to a substantial 2.0” diameter anchoring node situated near the base to act as an unyielding internal fluid dam.

• High-Leverage Retention Valley: Drops down into a 1.0” long by 1.3” diameter base neck, letting sphincter muscles seat themselves precisely for optimal hands-free anchoring and pelvic comfort.

• Flared Safety Flange: Completed with a wide, flared flange base to act as a dependable external stop and provide worry-free positioning.
  

👑 Bob's Choice Recommendations

• Experience Level: Advanced Intermediate / Advanced. An exceptional choice for seasoned size and depth enthusiasts who love the dynamic, ribbed texture of the CT-103 series but want a shorter length option paired with a substantial 2.0-inch threshold retention lock. Due to its girth and intensity, this model is not recommended for beginners.

• The Prime Durometer Recommendation: Because a solid profile hitting a robust 1.3" shaft width and a 2.0" retention ball carries a highly substantial amount of physical weight and material mass, Bob’s prime recommendation for the GRB 103 is our #00-50 (soft) or #10 if you want it a little more firm.

Color Options: #18 and #30 are available in pure translucent. #00-50 and #10 base colors are translucent white and can be mixed with any standard color.
