Rev-A-Shelf bottom mount shaft is a replacement hardware component for select wood Lazy Susan shelf setups. This Rev-A-Shelf part is identified as manufacturer part 4BM1-04-52 and is described as a bottom mount shaft for one wood tray. Buyers searching RS4BM1-04-52, rev a shelf, or revashelf are typically replacing worn or missing wood lazy susan hardware in an existing cabinet. Product data states that bottom mount hardware can only be used with Rev-A-Shelf shelves. Rev-A-Shelf also states that its hardware kits for wood or melamine custom shelving are tested to meet and exceed BHMA Class-I specifications of 20 lb per square inch at 100,000 cycles. For a repair or planned cabinet build, this wood susan shaft is intended for custom Lazy Susan applications that need compatible bottom mount lazy susan hardware from the same brand.
Key specs to confirm: This product is a Rev-A-Shelf bottom mount shaft for one wood tray. Before ordering, confirm that your cabinet uses a bottom-mount Lazy Susan setup and that the shelves are Rev-A-Shelf shelves, because product data states this hardware can only be used with Rev-A-Shelf shelves. Confirm whether your application is for one wood tray, not a different tray count or material. Also verify the exact part reference 4BM1-04-52 against your existing hardware or project documentation. If you need dimensions, mounting details, load information for this specific component, or any compliance details beyond the verified hardware-kit statement, confirm those points with the manufacturer or technical documentation.
What's included: Verified data identifies this item as one bottom mount shaft sold each. No additional brackets, trays, bearings, or mounting fasteners are specifically listed in the verified product data, so included items beyond the shaft should be confirmed before purchase.
What to verify before ordering: Confirm Rev-A-Shelf shelf compatibility, bottom-mount configuration, one-wood-tray application, part number match, and whether your project also needs other lazy susan hardware kit components that are not stated as included.
A lazy susan replacement shaft is usually purchased when an existing cabinet still has usable shelves but the rotating hardware needs service. In that situation, buyers want to avoid replacing the full interior if a single component can restore function. This Rev-A-Shelf part is intended for that kind of targeted repair when the cabinet uses compatible Rev-A-Shelf shelves and a bottom-mounted arrangement.
One common scenario is a kitchen cabinet with a single wood tray that no longer operates as intended because the shaft assembly is missing, damaged, or being updated during a remodel. Another scenario is a custom cabinet build where the installer is sourcing wood lazy susan hardware for a new shelf setup and needs a brand-matched component rather than a mixed hardware set. In both cases, the most important fit point is clear in the product data: bottom mount hardware can only be used with Rev-A-Shelf shelves.
Buyers searching Rev-A-Shelf lazy susan parts often need to confirm more than the brand name. They also need to confirm tray count, shelf material, and mounting style. This product is described as a bottom mount shaft for one wood tray, so that detail matters. If your cabinet uses melamine shelves, multiple trays, or a different mounting style, review the technical documentation before ordering. If you are replacing an older component, match the manufacturer part number 4BM1-04-52 whenever possible.
The verified web description also notes that Rev-A-Shelf hardware and hardware components allow flexibility, strength, and aesthetic value for custom applications. For installers, that means this type of part is meant to support custom cabinet work rather than a one-size-fits-all approach. When using RS4BM1-04-52 or another wood susan shaft in a service call, confirm the existing shelf system first so you do not order a shaft that fits the brand family but not the exact cabinet layout.
When comparing bottom mount lazy susan hardware, buyers usually care about compatibility first, then component scope, then whether the part aligns with a custom shelving system already in place. This Rev-A-Shelf bottom mount shaft gives a clear compatibility signal because the product data states it is for one wood tray and for use with Rev-A-Shelf shelves. That is more useful than a generic hardware listing that leaves shelf brand or tray type unclear.
Another practical comparison point is whether the listing identifies the product as a complete kit or as a single component. Here, the verified data supports a component-level purchase. The item is sold each and described specifically as a bottom mount shaft. That helps buyers who only need one replacement part and do not want to assume a full lazy susan hardware kit is included.
Brand consistency also matters in cabinet hardware. A Rev-A-Shelf component is often preferred when the existing shelves are already from Rev-A-Shelf, because the product data limits use to Rev-A-Shelf shelves. That reduces the risk of mixing unrelated parts in a cabinet interior. The verified performance statement for Rev-A-Shelf hardware kits for wood or melamine custom shelving may also help buyers evaluating the broader hardware family, though the exact performance details for this single shaft component should still be confirmed when required for a job file or specification review.
For trade buyers and serious DIY users, the safest path is to compare by mounting style, tray count, shelf material, and exact part number. If any dimension, fastener, or load requirement is critical to your project, confirm it before ordering rather than assuming interchangeability across all Lazy Susan systems.
