48 mm Pressed Jockey Wheel Clamp with 3.0 mm Thickness and Folding Handle

K-3F is specified for a 48 mm jockey-wheel or prop-stand tube class, with 3.0 mm thickness and a folding-handle clampconfiguration.

The exact product images verify a formed/pressed split-clamp body, circular tube seat, threaded compression mechanism, pivoting/folding lever with black grip and a trailer-side mounting base. Unlike K-5, the K-3F images do not show a substantial cast base.

Construction Boundary

K-3F Is Visually a Pressed / Formed Split Clamp—not the Cast-Base K-5

Current 48 mm clamp catalogs separate pressed steel split clamps from cast-base or cast-steel clamps. K-3F's exact photographs align with the pressed/split architecture, while K-5 is explicitly supplied as a cast clamp.

No material grade or surface treatment is supplied for K-3F, so the page uses pressed / formed as a structural description without asserting a specific steel grade, zinc plating or galvanizing specification.

48 mm Tube Fit

48 mm Is the Primary Compatibility Dimension

The supplied “Suitable for: 48MM” matches the way current jockey-wheel clamp suppliers classify these parts by tube/shaft outside diameter. The K-3F clamp should therefore be selected around a compatible 48 mm round jockey-wheel or prop-stand tube.

Nominal diameter alone does not define every fit case. Ribbing, sleeves, weld seams, coatings and local tube deformation can change how the clamp seats.

3.0 mm Published Thickness

The 3.0 mm Specification Distinguishes K-3F from K-5's 3.5 mm Product Specification

K-3F is supplied with Thickness: 3.0MM. This is kept at product-specification level because no dimensioned drawing identifies which individual formed section is the measurement reference.

The value should not be assigned to the handle, pin, threaded fastener, washer or every visible wall in the assembly.

Folding Handle

The Pivoting Lever Can Be Repositioned after Clamp Adjustment

The exact photographs show a lever connected through a pivoting head, with a black grip at the operator end. This supports the supplied folding-handle description and helps reduce permanent handle projection after adjustment.

Handle length, pivot-pin dimensions, tightening torque and clamp-force target are not published.

Trailer-Side Mounting

The Base Provides a Bolt-On Interface to a Suitable Drawbar or Chassis Bracket

Visible mounting holes in the base support a bolt-on installation concept. The actual trailer member, bolts and any backing structure must be appropriate for the complete jockey-wheel reaction.

Mounting-hole diameter, centers, bolt grade and required frame thickness are not supplied for K-3F and are not copied from market examples.

K-3F vs K-5

Same 48 mm Tube Class, Different Clamp Construction

K-3F owns the pressed/split clamp intent with a 3.0 mm product thickness and folding handle. K-5 owns the cast-clamp intent with 3.5 mm published thickness and folding handle.

That split is more useful for B2B sourcing than publishing two nearly identical “48 mm jockey wheel clamp” pages.

K-3F FAQ

Buyer Questions for the 48 mm Pressed Clamp

What is K-3F?

It is best described as a 48 mm pressed/split jockey wheel clamp with a folding handle.

How is K-3F different from K-5?

K-3F uses a pressed/formed split-clamp architecture and 3.0 mm published thickness; K-5 is the cast-clamp model with 3.5 mm published thickness.

Does it fit a 48 mm jockey wheel?

48 mm is the supplied compatible tube class. Actual fit should still be confirmed against the tube profile.

Is it zinc plated?

No surface-treatment data was supplied, so the page does not publish a zinc-plated claim.

Production Visibility for Trailer Clamp and Jockey-Wheel Hardware Programs

GOODIN supports B2B sourcing with real production, component-handling and workshop inspection visibility. Product-specific material grade, forming process, surface treatment, fastener specification, tube-fit tolerance and clamp-load validation should still be confirmed against current production documentation.

B2B Clamp RFQ

Specify the 48 mm Tube, Pressed-Body Geometry and Folding-Handle Requirement

For quotation, provide tube OD/profile, thickness reference and tolerance, mounting-hole pattern, trailer-member geometry, material/finish requirement, folding-handle envelope, clamp-slip/load validation criteria, quantity, packing and destination market.

Clamp Application Profile

Use K-3F for Compatible 48 mm Jockey-Wheel or Prop-Stand Tubes Where a Pressed Split Clamp and Folding Handle Suit the Layout

K-3F provides adjustable retention for a 48 mm round support tube while the trailer-side base remains fixed to the drawbar or chassis bracket.

Tube Compatibility

Confirm 48 mm OD at the Actual Clamping Zone

Measure the tube where the clamp will grip. Ribbed, sleeved, coated or locally distorted tubes may not behave like a smooth 48 mm shaft even when the nominal jockey-wheel size is 48 mm.

Handle Clearance

Allow Room to Tighten the Clamp and Reposition the Folding Lever

Mount the clamp where the operator can access the handle without interference from the coupler, brake hardware, drawbar members or body panels. The pivoting handle helps manage space but does not eliminate the need for a clear operating envelope.

Clamp Security

Secure the Tube against Slip without Applying Unverified Extra Leverage

Use the supplied handle mechanism as intended and verify that the tube remains secure in the selected position. No tightening torque or clamp-force specification is provided, so improvised handle extensions should not be used.

Trailer Structure

The Mounting Base, Fasteners and Drawbar Form One Load Path

The clamp's holding function depends on the mounting base being attached to a suitable trailer structure. Bolt sizes and hole centers should come from the K-3F production drawing rather than from competitor clamps.

Travel Position

Raise and Secure the Jockey Wheel before Road Travel

After hitching, place the jockey-wheel assembly in its approved travel position and verify adequate road and trailer-component clearance. K-3F does not define the jockey wheel's load rating or travel range.

Inspection

Inspect the Formed Body, Tube Seat, Pivot, Threads and Mounting Hardware

Stop use if the clamp body distorts or cracks, the handle pivot or thread is damaged, the tube slips under normal tightening, or trailer-side fasteners become loose.
