The construction involves two main components: the door slab and the specialized hardware system. The door itself can be made from standard materials like hollow-core or solid-core wood(lightweight for easier sliding), but its width must be specifically sized to fit the pocket opening. The heavy-duty hardware kit is essential, featuring a robust overhead track,roller hangers that attach to the top of the door, a floor guide to prevent lateral sway, and a heavy-duty doorframe for the opening side. The surrounding wall structure is also a key material consideration; the pocket frame is typically built from standard lumber (like 2x4s or 2x6s) during rough framing, and finished with drywall. The quality of the hardware—often steel or nylon rollers and a stainless steel track—directly determines the door's smoothness, quietness, and long-term durability.
