3" Locking Caster from Fastcap is a stem-mounted caster designed for builders hardware applications, so it suits shop fixtures, carts, and stands that need controlled mobility. The stem and socket mount class means this caster is built to fit stem-and-socket style mounting points, which helps keep alignment predictable when you are fabricating repeatable frames. The FP-3 IN LOCK CASTER identifier ties this caster directly to the Fastpipe system name, so matching it to existing Fastpipe-based layouts stays straightforward for future additions or changes. A 3 inch diameter caster offers a practical balance between maneuverability and footprint on typical shop floors, which supports easy repositioning of fixtures without overbuilding the base. The locking function lets you stop movement at the work position, which helps stabilize loads during cutting, assembly, or finishing tasks where unwanted rolling would interfere with accuracy.
This Fastcap 3" Locking Caster is classified as stem and socket mount, so it is intended to be installed by inserting the stem into a compatible socket in the fixture or cart base. That mounting style keeps the footprint small at the frame corners, which can be important on narrow stands or compact pipe-based racks. As a stem mounted caster in the builders hardware category, it is aligned with typical woodworking and shop projects where casters need to be integrated directly into wood, metal, or pipe structures. The locking capability allows the wheel to be secured when the cart or fixture is in position, which supports steadier work during operations that benefit from reduced movement, such as assembly, fastening, or sanding.
The FP-3 IN LOCK CASTER part is described as a Fastpipe Locking Caster, so it aligns naturally with Fastpipe-based shop fixtures that use stem and socket mount points at the base. As part of the stem mounted casters category, it is well suited to applications where the caster stem engages into pre-installed sockets on frames or legs, such as rolling workstations, assembly carts, or storage racks that need straightforward mobility. The 3 inch caster size works effectively on typical shop floor surfaces that woodworking operations use, giving enough diameter for smooth rolling while keeping the overall height of the fixture manageable. Because the load capacity is listed as 100 lbs per pair, this caster fits lighter-duty to moderate shop assemblies where controlling weight per pair of casters helps maintain an appropriate working margin for the overall build.
The locking function on this 3" Locking Caster lets the user restrict wheel movement at the workstation, which helps maintain consistent positioning when repeating cuts, fastening patterns, or alignment-critical assemblies. The stated load capacity of 100 lbs per pair gives a clear baseline for planning caster layouts, so builders can distribute expected loads across multiple casters in a way that aligns with the rating and helps avoid overloading any pair. Being part of the stem and socket mount product class means the caster is designed around a repeatable stem-and-socket interface, which supports consistent leg geometry when fabricating multiple identical carts. As a Fastpipe Locking Caster under the Fastcap brand, it fits into a recognizable naming structure that simplifies reordering the same caster for expansions, replacements, or matching new fixtures to existing mobile equipment in the same shop.
The 3" Locking Caster has a load capacity of 100 lbs per pair, which guides how much weight two casters should support when designing carts or fixtures.
The Fastpipe Locking Caster is a stem mounted caster in the stem and socket mount class, so it is intended to install via a stem engaging a matching socket.
This stem mounted caster is categorized under builders hardware and stem mounted casters, making it suited to shop fixtures, carts, and stands needing controlled mobility.
The locking feature on the 3" Locking Caster lets you hold a cart or fixture in position, which supports steadier work during assembly or other operations.
FP-3 IN LOCK CASTER is the manufacturer part number for this Fastpipe Locking Caster, which links it to the Fastcap Fastpipe naming convention for reordering.
The 3 inch caster size adds moderate height, balancing clearance and stability so carts or fixtures stay relatively low while still rolling over typical shop floors.
The Fastcap 3" Locking Caster, identified as FP-3 IN LOCK CASTER, offers a stem and socket mount design with a 100 lbs per pair load capacity, so it fits light to moderate shop builds where stable rolling and positive locking matter. As a stem mounted caster in the builders hardware category, it aligns with woodworking and shop fixtures that depend on compact mounting and predictable alignment. For projects built around Fastpipe or similar layouts, this Fastpipe Locking Caster gives a defined part to standardize on when creating or expanding mobile racks, carts, or stands.
