View HSSF productBrophy HSSF, HSAB & HSWB Truck Camper Hold-Down Parts Guide
Brophy's super-heavy-duty truck camper hold-downs secure to compatible pickup bed rails using under-rail clamps and threaded T-bars. Unlike stake-pocket tie-downs, these sets attach without drilling. The straight HSSF, angled HSAB and Ford-specific HSWB models are different assemblies, so check the truck bed and camper anchor locations before choosing one.
Brophy's original mounting drawings
The factory illustrated hold-down installation sheet (PDF) shows how the clamp fits beneath the pickup bed rail, the protective pad positions and the front/rear camper tie-down placement. The drawing specifies at least 2 inches of open space below the bed-rail lip.
The Brophy hold-down product chart distinguishes the straight, angled and Ford-only sets.
Which Brophy hold-down fits your truck bed?
| Part number | Hold-down style | What to check |
|---|---|---|
| HSSF | Standard black, straight-profile bed-rail clamp | Rail clearance, camper anchor position, model exclusions |
| HSAB | Black bed-rail clamp with angled connection tab | Angle and access around truck fender and camper attachment |
| HSWB | Special black set for 2019+ Ford F-250/F-350 | Ford-specific pickup bed, Front/Back labeled positions |
Important model distinctions: Brophy specifies HSWB for 2019-and-newer Ford F-250/F-350 pickups; HSSF and HSAB are not substitutes for those applications. Brophy also excludes HSSF/HSAB on 2019-and-newer Ram trucks with the specified tool-box-style bed. Match the original truck bed structure and vehicle owner's camper-mounting guidance.

Bed-rail clearance and installation details
Measure at least 2 inches between the pickup sidewall and bed-rail lip and confirm that the clamp plate can seat directly against the metal rail. Brophy states that drop-in/slide-in bed liners interfere with these mounts unless the liner is removed or relieved at all four clamp positions; sprayed-on bed liners are allowed. Do not fasten a clamp over an unsupported trim or liner.
Some trucks require Brophy 2007 extra-long T-bar bolts, sold separately. Brophy names certain 2020-and-newer Chevrolet/GMC 2500/3500 models and the 2006 Dodge Ram 1500 4×4. Verify your exact truck and the amount of thread engagement before installation.
Position the front clamps ahead of the camper's front anchor eyebolts and the rear clamps slightly behind their eyebolts, as shown in the manufacturer drawing. HSWB components marked Front and Back belong in those respective positions. Brophy specifies that these bed-rail hold-downs are not for off-road use.
Clamp-on versus older stake-pocket tie-downs
On older trucks with suitable stake pockets, Brophy also sells TDSF and TDBP stake-pocket tie-downs. Those require drilling and use a different set of fasteners; they are not a no-drill alternative to HSSF/HSAB. Browse camper tie-down systems and camper turnbuckles for related equipment.
