SSND-SPIKE
Recommended for open bore options
The SSND-SPIKE is a textured silicone sounding rod engineered for dynamic internal feedback and gradual urethral dilation. Designed with a slightly rounded four-sided tip, this profile navigates initial insertion smoothly before introducing tactile ridges along its working length. Classified as a Beginner urethral sound based on its 9.5mm (28 Fr) shaft size, it features an integrated retention valley and flared base to ensure structural security and precise positioning during wear.
Anatomical Sizing & Mechanics
-
Entry Tip: Softly rounded, blunted four-sided tip designed to ease past the meatus with minimal resistance.
-
Shaft Progression: Uniform 9.5mm (28 Fr) textured main working length provides constant tactile engagement.
-
Peak Diameter: 10mm flared retention flange creates an anchor point just above the main shaft.
-
Retention Valley: 8mm narrow contour designed to sit comfortably at the entry for extended placement.
-
Safety Flange: Integrated base prevents over-insertion and provides a firm anchor for safe retrieval.
Anatomical Depth Guide Available in total lengths of 8", 10", and 12". The initial insertable section engages the penile urethra, while the full length reaches into the prostatic urethra and bladder region. Intermediate to advanced technique is recommended when advancing full-length models into deeper canal structures.

👑 Bob's Choice Recommendations:
-
Experience Level: Beginner
-
The Prime Durometer Recommendation: #10 (medium) silicone density as the primary choice for structural integrity, easier insertion without bowing, and high-definition tactile feedback.
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.
