D. Spike (optional) Installation Model CM-1401: Remove the Rubber Cap on the end of the leg by twisting and working it forward – it fits snugly in order to prevent it from coming off accidentally. After it is removed, a thread is exposed at the tip of the leg, into which a Long or Short Spike can be screwed (for use on scratch- sensitive surfaces, remove Spike and replace Rubber Cap).
