Defining the HS-H042 Rear Rack as a Complete Retail Model
Define the HS-H042 platform, spring arm, lower support frame and bicycle fit as separate parts of one retail product specification.
The HS-H042 combines a top cargo platform, a spring arm and a four-member support frame with lower clamps. These visible parts should appear separately in a retail or OEM specification because they answer different questions. The platform defines the cargo area, the spring arm retains an item on top, and the lower structure determines how the rack reaches the bicycle frame. One model name alone cannot describe all three.
State what belongs to the cargo area

The top view shows a tubular platform with cross-members and a spring arm that can lift above the deck. This arm is part of the rack’s visible cargo-control layout. Product copy should identify it plainly and use the same image throughout the sales record.
The photograph also shows a rear red reflector element. A buyer who needs that item in the supplied configuration should name it in the requirement list and confirm it on the approved sample. An image can show the reviewed sample, but the written order record decides what must be supplied.
Keep the support frame in the fit specification

Below the platform, curved side members and straighter braces form the rack support. Lower clamps and fasteners sit at the ends. A separate close image shows a sliding joint where a support member passes through a black block with a fixing screw. These details belong to the bicycle-fit section of the specification.
For a target bicycle, record the lower attachment locations, the space beside the tire and the distance up to the platform. Add the position of any mudguard and rear brake hardware. The sample review should confirm that the platform remains centered while the support members meet the intended frame areas.
The current HS-H042 product record lists aluminum-alloy construction, a 26 to 29 inch size field and a catalog maximum of 25 kg. Keep those catalog fields beside the approved component list and bicycle-fit record. This gives purchasing, inspection and sales teams the same model definition.
