GRB 35

Discover an exceptional blend of precision depth control and multi-stage fluid containment with the GRB 35. Expertly engineered within our premier Graduated Retaining Ball (GRB) design series, this 9.0-inch medium-length silicone colon nozzle is designed specifically for new or frequent users who prefer a ball-style configuration with a more moderately sized, contoured expansion profile. Featuring dual independent retention zones along the shaft, this versatile appliance allows you to customize your experience by anchoring the nozzle securely at multiple depths while maintaining an exceptional, leak-proof fluid seal.

Sigmoid Comfort Reach & Dual-Zone Anchoring: The architectural layout of the GRB 35 is sculpted to maximize mechanical retention options while keeping internal expansion completely gentle and uniform. It guides initial placement with an extra-long, 4.5-inch tapered entry shaft that starts at a sleek 0.75 inches and gradually scales to 1.0 inch in diameter. Beyond this entry zone, the profile drops into a tight 0.75-inch First Retention Valley for a secure, shallower anchor, before swelling into a beautifully contoured, 1.4-inch (35mm) Elliptical Expansion Ball. Once past this primary node, the profile tapers back down into a Full Retention Valley measuring a comfortable 0.85 inches right before the base. At 9.0 inches in overall length, the tip safely accesses the lower sigmoid colon to promote a smooth filling experience and actively eliminate early cramping, allowing your muscles to rest effortlessly over your chosen retention zone.

Anatomical Design & Dimensions:

• Total Length: A highly stable, medium-profile 9.0” overall length.

• Sigmoid Placement Comfort: Designed to safely reach into the lower sigmoid colon, ensuring a deeper fluid distribution that minimizes early muscle contraction and cramping.

• Extended Tapered Shaft: Features a smooth, 4.5” long rounded entry tip starting at a sleek 0.75” diameter and graduating up to 1.0” to guide initial placement with minimized resistance.

• Dual-Zone Retention Valleys: Features a tight 0.75” first groove and a 0.85” secondary neck, giving users two independent, hands-free locking depths.

• Elliptical Expansion Ball: Smoothly swells into a contoured 1.4” (35mm) maximum diameter retaining node to act as an unyielding internal fluid dam.

• Secure Safety Base: Anchored by a stable 1.5” diameter base flange to prevent over-insertion and provide absolute hands-free confidence.

👑 Bob's Choice Recommendations

• Experience Level: Advanced Beginner to Intermediate. An outstanding choice for rising users who want a highly guided sigmoid tube that offers multiple independent depth options and a moderate, body-conforming expansion zone.

• The Prime Durometer Recommendation: For a multi-valley, precision piece like the GRB 35, Bob highly recommends ordering in our #10 (medium) composition. This density provides the absolute best structural definition, ensuring the dual retention valleys hold their distinct depths and the 4.5-inch entry shaft maintains excellent column strength and guiding alignment during placement.

Color Options: #18 and #30 are available in pure translucent. #00-20, #00-50, and #10 base colors are translucent white and can be mixed with any standard color.
