The listing is for set of 4 pieces carpet spikes. The length of each spike is 36mm. They were removed from Atacama stands. They are M6 thread size but they will not fit B&W speakers because the thread step is larger. I’m sure they will fit many other speakers/stands with M6 size large-step thread. The spikes are in used condition. They may have some minor signs of rust. Please inspect photos. If you need more than 4 pieces, please multiply the quantity during the checkout. Quick dispatch.
