MOUNTING SYSTEMS roof hook 170-7-40 – 2-way adjustable

The Mounting Systems end clamp is a specialised fastening element that secures the end of a row of solar modules to the substructure. In this version, it is designed as a universal clamp that flexibly covers module frame heights from 30 to 40 mm. The specification "40 mm" refers to the width of the clamping surface or the length of the clamping body to ensure optimum force distribution on the frame.Thanks to the sophisticated design, the clamp automatically adapts to the respective frame thickness when tightened. This makes it an extremely efficient solution for installers, as only one clamp model needs to be stocked for different module types.Highlights at a glanceVariable clamping range: Suitable for all standard solar modules with a frame height between 30 mm and 40 mm.High stability: The 40 mm wide clamping surface ensures a secure hold and protects the module frame against point loads.Robust materials: Made from weather-resistant aluminium and stainless steel screws, ensuring permanent corrosion resistance.Easy adjustment: The elongated hole or integrated spring allows the clamp to be precisely positioned and tightened at the end of the rail.Universal compatibility: Suitable for standard Mounting Systems profile systems and comparable aluminium mounting rails.Secure row termination: Ensures that the outer modules remain firmly attached to the rail even at extreme wind speeds.Areas of applicationThe end clamp is used exclusively at the outer ends of a module field:Photovoltaic roof installationsFor securing the first and last module of a row on pitched or flat roofs.Single module installationFor installations of individual modules (e.g. balcony systems), a total of four end clamps are required, as there is no module transition.Commercial PV parksFor use in large-scale systems where fast and reliable installation of the module termination is required.Installation & safety instructionsCorrect positioningThe clamp must be flush with the module frame. Ensure that the clamping foot is securely anchored in the mounting rail slot.Tightening torqueTighten the screw with the torque recommended by the system manufacturer (usually between 8 and 10 Nm) to achieve optimum clamping force without deforming the material.Overhang of the railAllow the mounting rail to protrude approx. 2–5 cm beyond the module to provide sufficient space for the end clamp to anchor stably. Properties CategoryEnd clamp alu natural Clamping range (frame height)30 – 40 mm MaterialAluminium (high-strength) Colour / FinishAlu natural (silver) Clamp length40 mm Area of applicationEnd fastening of the module field CompatibilityMounting Systems rail profiles Mounting typeClick or screw fixing Weather resistanceUV-resistant and corrosion-resistant  FAQs about the Mounting Systems end clampCan I use this clamp between two modules as well?No.Between two modules, centre clamps must be used as these fix both frames at the same time. The end clamp is shaped on one side only to hold just one frame at the end of the rail.Does the clamp fit both 30 mm and 40 mm frames equally?Yes.The mechanism is designed so that the clamp can be continuously tightened within this range. You just need to screw in the bolt until the clamping arm rests firmly on the module frame.Is this clamp also available in black?Yes.For full-black modules, Mounting Systems also offers this model in a black anodised version, so the fastening is not visually conspicuous on the dark frame.Is the clamp supplied as a set with screw and sliding block?As a rule, yes.Most variants are delivered as ready-to-install sets. However, please check in advance whether the included sliding block or click block (EC) matches your specific rail profile.

The Mounting Systems centre clamp is a universal connecting element for safely securing two adjacent solar modules to a substructure. This version is designed as a universal clamp and flexibly covers module frame heights from 30 to 40 mm. The specification "40 mm" refers to the width of the clamping surface, which ensures optimal load distribution on the frame edges.Thanks to the variable clamping range, the component automatically adapts to the respective frame thickness when tightened. This reduces complexity in material planning, as only one type of clamp is needed for various module generations.Highlights at a glanceFlexible clamping range: Suitable for solar modules with frame heights between 30 mm and 40 mm.Wide contact surface: The 40 mm wide clamping jaw ensures a stable hold and prevents damage to the module frame by localised pressure.High corrosion resistance: Made from high-quality aluminium and stainless steel screws for long-lasting resistance to weathering.Efficient installation: Allows simultaneous fixing of two modules with only one fixing point, reducing installation time per kilowatt-peak ($kWp$).Universal compatibility: Precisely fits common Mounting Systems profile systems as well as many cross-brand aluminium mounting rails.Symmetrical load distribution: The design ensures uniform contact pressure on both adjacent module frames.Areas of applicationThe centre clamp is used within a module field for connection:Photovoltaic rooftop systemsStandard fixing for pitched roof systems to securely connect rows of modules together.Commercial PV systemsUsed in large projects where the speed and reliability of components are critical.Multi-row module fieldsWherever more than one module per rail row is installed and a defined space (module gap) is required between the units.Installation & safety instructionsCentringThe centre clamp must be positioned exactly between the two module frames. Make sure that both frames are covered evenly by the clamp.Tightening torqueTighten the stainless steel screw to the recommended torque (usually 8–10 Nm). Too little tightening jeopardises storm resistance, too much tightening can deform the frame.Earthing / potential equalisationObserve the applicable regulations regarding earthing of the mounting system. Some centre clamps feature integrated earthing pins that pierce the anodised coating of the frame. Properties CategoryCentre clamp natural aluminium Clamping range (frame height)30 – 40 mm MaterialAluminium (high-quality anodised/natural) Colour / FinishNatural aluminium (silver) Clamp length40 mm Area of applicationConnection between two solar modules CompatibilityMounting Systems rail profiles Mounting methodClick or screw fixing Weather resistanceVery high / corrosion-resistant  FAQs on the Mounting Systems centre clampCan I use this clamp for any solar module?Yes, provided the frame height is in the range of 30–40 mm.Most modern high-performance modules have frame thicknesses of 30 mm, 35 mm or 40 mm, making this clamp almost universally applicable.Is the distance between the modules specified by the clamp?Yes.The centre bar of the clamp creates a technical gap between the modules (usually approx. 20 mm). This gap is necessary for the thermal expansion of the rails and modules.Is the clamp supplied complete with sliding block?Usually, yes.The clamp is usually supplied as a set including screw and sliding block or click block. Check in advance if the block is compatible with your specific rail profile groove.Is this model also available for black module frames?Yes.For an aesthetically pleasing installation of full-black modules, this clamp is also available in a black anodised version available.
