Type 400 and 170 Mated Set Mushroom Lock

Type 400 may also be mated to itself when higher-than-normal fastening strength is needed. It is suggested that the 400/400 combination be tested for suitability for particular applications before use.Type 170 Mushroom Lock has approximately 170 stems per square inch. It is designed to mate to Type 400. Type 170 will also mate with the loop side of Hook and Loop.
