48mm Cast Jockey Wheel Clamp with Folding Handle | K-5
Thickness:3.5MM
CAST CLAMP WITH FOLDING HANDLE
48 mm Cast Jockey Wheel Clamp with 3.5 mm Thickness and Folding Handle
K-5 is specified for a 48 mm jockey-wheel or support-tube class, with 3.5 mm thickness and a cast clamp with folding handleconfiguration.
The exact product images verify a substantial cast base/clamping section, circular tube seat, upper formed metal housing, threaded compression mechanism, folding lever with black grip and multiple trailer-side mounting holes.
“Cast Clamp” Is Published; the Exact Casting Alloy and Surface Finish Are Not
The supplied description explicitly states CAST CLAMP WITH FOLDING HANDLE. The real product images also show a textured cast base/clamp section combined with formed upper hardware.
No cast-iron grade, cast-steel grade, tensile property, heat treatment, zinc plating, galvanizing or coating specification is supplied. This page therefore does not infer those details from visually similar market products.
K-5 Targets the Established 48 mm Jockey-Wheel / Prop-Stand Tube Class
Current trailer-parts suppliers widely organize jockey-wheel clamps by tube diameter, and 48 mm is one of the most common commercial sizes. The supplied “Suitable for: 48MM” therefore aligns directly with market naming for jockey-wheel and prop-stand clamps.
Actual fit should still be checked against the supported tube's measured outside diameter, surface condition, ribs/serrations and any weld seam or sleeve in the clamping zone.
The Cast Section Provides the Main Tube-Support and Trailer-Mounting Structure
K-5 visibly uses a heavier cast lower structure rather than the lighter formed clamp architecture seen on K-2. Current 48 mm market products distinguish cast clamps from pressed-steel clamps for exactly this structural reason.
The page does not label K-5 “heavy duty” as a formal rating because no clamp-force, slip-test or load capacity is supplied.
3.5 mm Is a Product Specification—but Not a Universal Thickness for Every K-5 Component
The supplied specification states Thickness: 3.5MM. Because K-5 combines cast and formed parts, this page preserves the value at product-specification level rather than assigning it to every cast wall, cover, lever, washer or mounting section.
A production drawing should identify the exact measurement reference if buyers require tolerance-controlled thickness data.
A Hinged Lever Can Fold Down after Clamp Adjustment
The exact product images verify a pivoting lever assembly with a black hand grip. The handle can rotate at its hinge so the operator can reposition it after tightening instead of leaving a long rigid lever projecting in one fixed direction.
Handle length, pivot pin diameter, operating torque, tightening torque and required clamp force are not published.
The Circular Seat and Compression Jaw Secure the 48 mm Tube against Vertical Slip
The visible semicircular geometry creates the support surface for the jockey-wheel or prop-stand tube. Tightening the threaded mechanism closes the clamp onto the tube and holds the selected vertical position.
K-5 does not establish the load capacity of the jockey wheel passing through it. Tube support rating, nose-weight rating and clamp-slip performance remain separate engineering parameters.
Multiple Base Holes Provide the Interface to a Compatible Drawbar or Chassis Bracket
The cast base visibly includes several through-holes for attachment to the trailer structure. Current cast 48 mm clamps are commonly bolted to trailer drawbars or chassis plates.
Exact hole count usable in each installation, hole diameter, center spacing, bolt size/grade, backing-plate requirement and required trailer-member strength are not supplied for K-5.
K-5 Occupies a Different Tube Size and Construction Intent from the 35 mm K-2 Clamp
K-2 targets a 35 mm tube class with 3.0 mm thickness and a formed iron clamp body. K-5 moves to the 48 mm tube class, 3.5 mm published thickness and a cast-clamp configuration with folding handle.
This makes tube diameter and construction type—not just model number—the primary purchasing distinction between the two GOODIN clamp pages.

Buyer Questions for the 48 mm Cast Clamp
What is K-5?
K-5 is best described as a 48 mm cast jockey wheel clamp with a folding handle.
What tube size does it fit?
The supplied suitable size is 48 mm. Actual fit still requires a compatible round tube profile.
Is K-5 a cast clamp?
Yes. “Cast clamp with folding handle” is part of the supplied product description, and the cast base/clamping structure is also visually evident.
Is every component 3.5 mm thick?
No. The supplied product thickness is 3.5 mm, but a drawing is needed before assigning that dimension to specific cast or formed sections.
Is the clamp zinc plated?
No surface-treatment specification was supplied, so no zinc/galvanized finish claim is published.
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 casting grade, formed-part thickness, surface treatment, thread specification, mounting geometry and clamp-load validation should still be confirmed against current production documentation.
