The 3 Stayput^® Shock Cord Knobs we make are designed to accept 6mm shock cord as used in our Shock Cord Loops. All 3 knobs are strong and well made with a smooth and rounded finish. We offer a standard nylon model, a premium nylon model with a neat fitting cap which hides the rivet or screw used to fix the knob, and lastly a low profile polished 316 stainless steel model for those who like a ‘bit of bling’. The nylon models are available in Black or White (other colours are also possible on request) and the 316 Stainless Steel knobs have a polished finish.
