Knuffi Edge Protection Type BB (Product Code 14011 / PB-14011) is engineered specifically for mechanical friction mounting on exposed industrial structural edges, flanges, and profiles. Achieving an optimal friction fit without mechanical fasteners or chemical adhesives depends directly on adhering to the profile’s internal channel dimensions.
Flange Thickness and Edge Profile Dimensions
The Type BB profile features an integrated grooved edge slot measuring exactly 8 mm (0.31 inches) in width and 19 mm (0.75 inches) in depth. The overall external profile measures 40 mm (1.57 inches) in width by 36 mm (1.42 inches) in height. This geometry is designed for push-on installation directly over exposed steel edges and structural components.
- Target Substrate Thickness: Optimized for steel sheets, structural plates, and profiles with a nominal thickness of 8 mm (approx. 5/16 in).
- Minimum Flange Insertion Depth: Requires an unobstructed flange depth up to 19 mm to allow the channel to seat fully against the substrate.
- Profile Length & Customization: Supplied in standard 1-meter (1,000 mm) sections that can be cut to custom lengths on-site with a utility knife or heavy shears to fit specific machinery or beam dimensions.
Structural Substrate and Equipment Compatibility
Knuffi Type BB provides protective edge buffering across a wide variety of industrial structural shapes and equipment assemblies. It is designed to mount securely onto raw or coated metal without requiring surface adhesive priming or drilling.
- Structural Steelwork: Directly compatible with I-beam flanges, T-beams, steel girders, channel sections, and structural angle profiles.
- Machinery & Enclosures: Suitable for open sheet metal edges, machine chassis guards, protective panels, and industrial equipment frames.
- Racking and Storage Infrastructure: Compatible with upright warehouse storage frames, low-clearance steel channels, mezzanines, and overhead transit gates.
- Internal Logistics & Mobile Assets: Acts as a physical buffer zone along transit corridors to absorb contact from automated guided vehicles (AGVs), pallet jacks, tow tuggers, and forklifts.
Edge Dimension Compatibility Reference
| Substrate Thickness | Compatibility Status | Fit Characteristic & Performance |
|---|---|---|
| < 7.5 mm | Incompatible (Undersized) | Insufficient friction grip; profile may slip, loosen, or detach during vibration or contact. |
| 8.0 mm (Nominal) | Optimal Fit | Full mechanical grip; non-adhesive pressure retention securely holds profile at full 19 mm depth. |
| > 8.5 mm | Incompatible (Oversized) | Forces excessive core spreading; risks tearing or permanently deforming the polyurethane foam core. |
Operational and Environmental Temperature Limits
The high-density polyurethane (PU) construction maintains its physical elasticity, impact absorption, and clip-on retention across an operational temperature range of -40°C to +100°C (-40°F to +212°F). This allows seamless installation in extreme thermal environments, including industrial cold storage warehouses, refrigerated processing areas, standard indoor distribution centers, and high-temperature manufacturing plants.
