GRB 75 12", 14",& 16"

Discover ultimate depth control and high-efficiency fluid containment with the GRB 75. Uniquely engineered as a specialized, medium-length modification of our classic CT-75 colon tube, this premium silicone appliance integrates an advanced low-profile retaining ball right ahead of the safety flange. This clever architectural layout offers a highly effective, hands-free solution that securely anchors the tube in place during use, completely removing the need for manual adjustment while administering solutions. Utilizing the exact same flexible, segmented barrel-style node design as the original CT-75, it allows the nozzle to flex and traverse the natural contours of the lower anatomy with exceptional ease.

Flexible Segmented Shaft & Low-Profile Retention Lock: The structural design of the GRB 75 is optimized to provide deeper fluid distribution while keeping the expansion curve perfectly uniform. It features a consistent 1.0-inch main shaft diameter that transitions into flexible, segmented barrel-style nodes that adapt dynamically to internal contours. 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 scales into an enlarged 1.3-inch diameter integrated retention ball before dropping into a smooth 0.9-inch diameter retention valley. Your pelvic floor muscles contract naturally over this groove, locking the tube hands-free against a stable 1.5-inch flared safety base.

Anatomical Design & Dimensions:

• Multiple Length Configurations: Select from three total lengths to perfectly match your comfort and experience level:

  • 12" Length: Provides an 11.0” maximum insertable depth.

  • 14" Length: Provides a 13.0” maximum insertable depth.

  • 16" Length: Provides a 15.0” maximum insertable depth.

• Tip options: Tip A is bumpy, and Tip B is tapered
  

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

• Segmented Shaft Profile: Features a consistent 1.0” main shaft diameter layered with flexible, barrel-style nodes to track internal curves smoothly.

• Integrated Retention Ball: Rises to an enlarged 1.3” diameter node situated near the base to act as an internal fluid dam.

• High-Leverage Retention Valley: Tapers smoothly down to a 0.9” diameter neck, letting sphincter muscles lock the tube in place hands-free without fatigue.

• Flared Safety Flange: Expands back up to a stable 1.5” diameter flared flange base for ultimate external security and a flush seal.

👑 Bob's Choice Recommendations

• Experience Level: Advanced Beginner / Intermediate. An exceptional choice for rising users who love the flexible, segmented dynamics of the CT-75 series but want shorter, more manageable length options paired with an integrated threshold retention lock.

• The Prime Durometer Recommendation: For an extended, multi-segmented colon tube like the GRB 75, Bob highly recommends ordering in our #10 (medium) composition. This density provides the vital structural column strength and guiding alignment needed to ease a long tube smoothly through internal contours without bending or buckling, while still retaining excellent, body-conforming flexibility.

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.
