INSERTA® ILR Lockstack D03 Retaining System includes stacking fasteners that eliminate the need to size and
cut thread stock for D03 sandwich stack assemblies. The system also
includes a novel isolation retainer that engages the fastener heads
to resist loosening during disassembly of the directional control
valve or other stack component(s) above. Use the Lockstack
system to reduce labor costs and sandwich assembly headaches, while
adding value and integrity to your sandwich assembly.
