GRB 122

Experience a the heavy-gauge internal fulfillment with the GRB 122. Specially engineered as an advanced, mid-length modification of our classic CT-122 colon tube, this premium 12-inch silicone nozzle features a ball retention system near the base. This unique modification delivers an effective, hands-free solution that anchors the tube securely following full insertion up to the safety flange, allowing for stable positioning while administering solutions. Sharing the same smooth, gently tapered tip and shaft configuration as our classic CT-122 colon tube, the GRB 122 prioritizes exceptional comfort and ease of use.

Heavy-Gauge Shaft Geometry & Monumental Threshold Lock: The architectural layout of the GRB 122 provides a massive mechanical advantage by offering an unyielding fluid-retention barrier right at the threshold. It features a robust, consistent 1.6-inch main shaft diameter that transitions into a gently tapered tip section designed 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 reduce early abdominal cramping. Right at the base, the profile swells into a prominent, enlarged 2.4-inch diameter retention ball before settling into a 1.0-inch long, 1.6-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 Smooth Shaft: Features a heavy-duty 1.6” main shaft diameter with a gently tapered head section for optimal internal comfort and guiding alignment.

• Prominent Retention Ball: Rises to a substantial 2.4” 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 1.6” 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. An exceptional choice for size enthusiasts who love the smooth, high-girth texture of the CT-122 series but want a shorter length option paired with a substantial 2.4-inch threshold retention lock. Due to its girth and intensity, this model is strictly not recommended for beginners.

• The Prime Durometer Recommendation: Because a solid profile hitting a robust 1.6" shaft width and a 2.4" retention ball carries a highly substantial amount of physical weight and material mass, Bob’s prime recommendation for the GRB 122 is our #00-50 (soft) composition. This density ensures the heavy-gauge silhouette feels beautifully yielding, plush, and compressible during placement, making this large-format profile significantly smoother to manage while retaining the baseline column strength required to slide into position smoothly.

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.
