35 mm Trailer Jockey Wheel Clamp with 3.0 mm Iron Body and Manual Lever

K-2 is a trailer clamp specified for a 35 mm application diameter, with 3.0 mm thicknessandIron as the supplied material description.

The exact K-2 product images verify a formed clamp body, circular 35 mm-class tube seat, manual tightening lever with black grip, threaded clamping hardware and a trailer-side mounting base with visible fastening holes.

Material Boundary

GOODIN Data Says “Iron”; This Page Does Not Silently Convert It to a Steel Grade

Current market listings for visually similar 35 mm jockey-wheel clamps commonly use “steel” or “pressed steel” terminology. The authoritative K-2 brief, however, states Material: Iron. This page preserves the supplied material description until a GOODIN material specification or certificate defines the actual grade.

The bright metallic appearance is visible in photography, but no zinc-plated, galvanized or other surface-treatment claim is made because no finish specification was supplied for K-2.

35 mm Tube Fit

The Clamp Is Intended for a 35 mm Jockey-Wheel or Prop-Stand Tube Class

The supplied “Applicable to: 35MM” aligns with current commercial 35 mm jockey-wheel clamp terminology, where the dimension refers to the supported round tube/shaft diameter. Current trailer-parts suppliers separately sell 35, 42, 48 and 60 mm clamp sizes, making tube diameter a primary purchasing specification.

Fit still depends on actual tube outside diameter, surface condition and clamp geometry. The page does not expand the compatibility claim beyond the supplied 35 mm class.

3.0 mm Clamp Body

Published 3.0 mm Thickness Defines the Main Formed Clamp Structure

K-2 is specified with a 3.0 mm thickness. This is a useful procurement distinction because current 35 mm clamp products are often differentiated by body construction and material thickness.

The current data does not define which individual panel or formed section is the measurement reference, so the page does not extend 3.0 mm to every visible component, lever, washer or fastener.

Manual Tightening Lever

The Lever Provides Tool-Free Clamping Adjustment at the Jockey-Wheel Tube

The exact image shows a bent metal lever with black grip connected to threaded clamping hardware. Turning the lever changes clamp pressure around the supported tube, allowing the jockey wheel or compatible stand to be secured at the required vertical position.

Handle length, thread diameter/pitch, tightening torque and required clamp force are not published for K-2.

Trailer-Side Mounting

The Base Must Be Fastened to a Suitable Drawbar or Chassis Structure

K-2 includes a formed mounting base with visible through-holes. This allows the clamp body to be fixed to a compatible trailer or caravan structure while the 35 mm jockey-wheel tube remains vertically adjustable in the clamp.

Mounting-hole count/spacing, fastener diameter, bolt grade, backing plate and required trailer-frame geometry are not supplied and should be confirmed before installation.

Jockey-Wheel Positioning

Clamp Security Matters in Both Working and Raised Travel Positions

A jockey-wheel clamp is responsible for holding the tube against vertical slip and unwanted movement once the operator has selected the required position. Before towing, the jockey-wheel assembly must also be raised and secured so that it cannot contact the road or interfere with adjacent trailer components.

K-2 itself is a clamp component. It does not establish the load rating, nose-weight capacity or travel range of the jockey wheel installed through it.

K-2 FAQ

Buyer Questions for the 35 mm Clamp

What is K-2?

K-2 is best classified as a 35 mm jockey wheel clamp for trailer/caravan mounting applications.

What tube size is it intended for?

The supplied applicable size is 35 mm, consistent with the standard commercial tube-diameter convention used for jockey-wheel clamps.

Is the body 3 mm thick?

The supplied clamp thickness is 3.0 mm. The page does not assume every individual component is 3.0 mm.

Is K-2 zinc plated?

No finish specification was supplied. The bright appearance alone is not used to publish a zinc-plated claim.

Does a 35 mm clamp define jockey-wheel capacity?

No. Tube fit and jockey-wheel load rating are separate selection parameters.

GOODIN Manufacturing

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 35 mm Tube Interface and Trailer-Side Mounting Pattern Together

For quotation, provide jockey-wheel/stand tube OD, required clamp thickness/material, mounting-hole pattern, bolt specification, drawbar/chassis geometry, required clamp-load or validation criteria, surface-treatment requirement, quantity and destination market.

Clamp Application Profile

Use K-2 to Secure a Compatible 35 mm Jockey-Wheel or Prop-Stand Tube to the Trailer Structure

K-2 is a manual clamp for a 35 mm round support tube. Its role is to provide adjustable tube fixation between the jockey-wheel/stand assembly and a suitable trailer or caravan mounting structure.

Tube Diameter First

Measure the Jockey-Wheel Tube before Treating “35 mm” as Compatible

Current clamp suppliers organize jockey-wheel mounting clamps by tube/shaft diameter. K-2 is specified for the 35 mm class, but actual fit should still be checked against the tube's measured OD, roundness and any ribs, weld seams, sleeves or coatings at the clamping area.

Do not use K-2 as a generic clamp for larger 42, 48 or 60 mm tubes.

Clamp Adjustment

Tighten the Lever until the Tube Is Secure without Using Improvised Extensions

The manual lever acts on threaded hardware to increase or release clamping pressure. Confirm that the tube cannot slide or rotate under the intended service condition before relying on the installed jockey wheel.

No tightening torque is supplied for K-2. Do not use cheater bars or other extensions to generate unverified clamp force.

Mounting Structure

The Clamp Base and Trailer Drawbar Must Work as One Structural Connection

Fasten the clamp only to a suitable trailer member or approved bracket. The clamp can hold the jockey-wheel tube only as reliably as the base, bolts and trailer structure support it.

Hole spacing, fastener size/grade and any backing-plate requirement are not currently published for K-2.

Working Height + Travel Stowage

Set the Tube Position for Support, Then Raise and Secure the Assembly before Road Travel

During hitching or uncoupled maneuvering, the clamp allows the jockey-wheel tube to be positioned vertically. Before towing, raise the jockey wheel to the approved travel position and verify clearance to the road, brake components, coupler and trailer frame.

Pre-Use Inspection

Inspect the Clamp Body, Lever, Threads, Tube Seat and Mounting Hardware

Stop use if the formed clamp body is cracked or distorted, the lever/threaded hardware is damaged, the tube slips despite normal tightening, or the trailer-side mounting hardware becomes loose.

Formal rejection limits and lubrication/service requirements should follow current GOODIN production instructions when available.

Use Boundary

K-2 Does Not Set the Jockey Wheel's Load Capacity

The supplied K-2 data defines tube size, thickness and material but does not provide a clamp load rating or jockey-wheel load rating. The complete installation must remain within the documented ratings of the jockey wheel, mounting structure and all connection hardware.
