Double Adjustable Tile Roof Hook
1. Product Overview
The Chudu Metal Stainless Steel Solar PV Double Adjustable Tile Roof Hook is designed for photovoltaic mounting systems installed on pitched tile roofs where greater installation flexibility is required.
Compared with a standard fixed tile roof hook, the double adjustable structure provides additional positioning and height adjustment, allowing installers to adapt the hook to different tile profiles, roof structures, rafter positions, and solar mounting rail heights.
The hook consists of a multi-hole base plate, adjustable connecting sections, a formed hook arm, and an elongated upper rail connection slot. During installation, the base plate is securely fixed to the roof rafter or timber supporting structure, while the adjustable sections allow the hook position to be optimized before final tightening.
The standard version is manufactured from SUS304 stainless steel for excellent corrosion resistance, mechanical strength, and long-term outdoor durability. SUS316 stainless steel and Q235 / Q235B hot-dip galvanized carbon steel versions are also available according to customer and project requirements.
The adjustable design makes this roof hook particularly suitable for residential and commercial pitched tile roof photovoltaic projects where conventional fixed hooks may not provide sufficient installation flexibility.

3. Product Features
1. Double Adjustable Design
The adjustable connection structure provides greater flexibility in both hook positioning and installation height, helping the hook adapt to different roof conditions.
2. SUS304 Stainless Steel Construction
The standard product is manufactured from SUS304 stainless steel, providing excellent corrosion resistance, strength, and durability for long-term outdoor photovoltaic applications.
3. Adaptable to Different Tile Heights
The adjustable structure helps compensate for differences in tile thickness, tile height, and roof construction.
4. Flexible Rafter Positioning
The adjustable mounting sections provide additional installation flexibility when the rafter or timber beam position does not perfectly correspond with the desired rail position.
5. Multi-Hole Base Plate
The wide base plate with multiple fixing holes provides various screw positions for secure attachment to the roof supporting structure.
6. Adjustable Rail Connection
The elongated upper slot allows additional vertical adjustment and convenient positioning of the aluminum solar mounting rail.
7. Secure Structural Support
The hook transfers the photovoltaic mounting load directly to the roof rafter or supporting timber instead of relying on the roof tile itself.
8. Pre-Assembled Structure
The adjustable components can be supplied pre-assembled to reduce installation work and improve on-site efficiency.
4.Why Choose a Double Adjustable Roof Hook?
Different tile roofs can vary significantly in tile height, profile, rafter position, and roof construction.
A conventional fixed roof hook provides limited adjustment and may not always align perfectly with the solar mounting rail.
The Double Adjustable Tile Roof Hook provides additional flexibility, allowing installers to modify the hook position before final fastening.
This makes it especially useful for:
- Different tile thicknesses and heights
- Uneven roof surfaces
- Different rafter positions
- Projects requiring precise rail alignment
- Retrofit photovoltaic installations
- Complex pitched tile roofs
5.Material Options
SUS304 Stainless Steel — Standard
SUS304 stainless steel is the standard material for the Double Adjustable Solar Tile Roof Hook. It provides a good combination of strength, corrosion resistance, durability, and cost performance.
SUS316 Stainless Steel — Optional
SUS316 stainless steel is available for coastal, high-humidity, or other projects requiring higher corrosion resistance.
Q235 / Q235B Hot-Dip Galvanized Carbon Steel — Optional
Q235 or Q235B carbon steel with hot-dip galvanized surface treatment can be supplied as a cost-effective alternative for suitable photovoltaic mounting projects.
6.Product Function
The Double Adjustable Solar PV Tile Roof Hook provides an adjustable structural connection between the pitched tile roof and the aluminum solar mounting rail.
The base plate is fixed to the roof rafter or timber beam using suitable structural screws. The intermediate adjustable connection allows the hook arm to be repositioned according to the roof tile and supporting structure.
The formed hook arm passes beneath the tile overlap and extends above the roof surface. The solar mounting rail is then attached to the elongated upper slot using a matching bolt and rail nut.
After the correct position and height are confirmed, all adjustable bolts are securely tightened to create a stable mounting point for the photovoltaic rail system.
7. Compatible Roof Types
Suitable for various compatible pitched tile roofing systems, including:
- Clay tile roofs
- Concrete tile roofs
- Curved tile roofs
- Pantile roofs
- Residential pitched roofs
- Commercial pitched tile roofs
- Other compatible tile roof structures
Final compatibility should be confirmed according to actual tile dimensions, roof profile, rafter location, and project requirements.
8. Installation Method
- Identify the roof rafter or suitable load-bearing structure.
- Carefully lift or remove the roof tile at the installation point.
- Position the multi-hole base plate on the rafter.
- Secure the base plate with suitable wood screws or lag screws.
- Loosen the adjustment bolts and set the hook to the required height and position.
- Adjust the hook arm so that it passes correctly beneath the roof tile.
- Tighten the adjustment bolts securely.
- Replace the roof tile and confirm correct positioning.
- Connect the aluminum solar mounting rail to the upper slotted hole.
- Adjust the rail height and alignment.
- Tighten the rail connection bolt and all adjustable fasteners.
- Continue installation of the rails, mid clamps, end clamps, and photovoltaic modules.
