The largest SLCD that Wired Bliss makes is a number 4. Each cam manufacturer has a definition of how large a "#4" sized cam actually is, but generally it means that the largest crack that it would fit in is 4 inches wide.

Our task is to design a device that fits in cracks 5 inches and larger, that also meets all the saftey, price and weight requirements listed below.

Note that nowhere have we stated that this device has to be an SLDC. In fact Wired Bliss has actually expressed a desire for a brand new anchor design that would, in Gene Hacker's own words, "set the industry on fire! " In our initial design, we tackled that challenge.

Here are the criteria that the client has set for this device...

Requirements:

  • Adaptable to 13 cm (5.1 in) cracks
  • Support dynamic loads up to 13kN (2900 lb)
  • Lightweight (less than 275 grams)
  • Cost effective to produce ($34 each)
  • Allow for one handed operation
  • Comparable range of motion (at least 4 cm)
  • Easy to carry
  • Compatible with standard climbing equipment
 

With these requirments in mind, we pursue a solution using our own criteria. As the old Engineering adage goe "Keep It Simple Stupid! " (KISS)

Design Philosophy

  • Examine the advantages and disadvantages of existing designs.
  • Pursue multiple design solutions
  • Emphasize simplicity in design, construction, and operation of device.
