The Renusol Roof Hook UK Plain Tiles/Slates HL is a high load capacity roof anchor engineered specifically for the UK market, designed for use on plain (flat) tiles and natural slate roofs where the installation needs to withstand higher wind suction and snow loading than a standard hook can provide.
Built from thicker, higher-strength steel than the standard UK Plain Tile hook, this HL (High Load) version delivers a 130% increase in suction (wind) load capacity, a 112% increase in pressure load capacity (self-weight and snow), and 53% more capacity for combined loads, making it the specified choice for sites exposed to higher wind zones or greater snow loading. The hook is supplied pre-assembled and without wood screws, and is compatible with the Renusol VarioSole+ mounting rail range.

Dimensions
ⓘ Please Note: This is the High Load (HL) version of the UK Plain Tiles/Slates roof hook, built from 8.0mm thick steel versus the 6.0mm thickness on the standard UK Plain Tiles/Slates hook (MPN 420181). Confirm the load requirements for the installation before ordering, as the two are not interchangeable on a like-for-like basis where higher load capacity has been specified.
ⓘ Please Note: This hook is supplied without wood screws and without wall/rafter fixings. Suitable wood screws must be ordered separately and selected to suit the rafter or batten construction being fixed into.
Key Features
Significantly Higher Load Capacity
Delivers a 130% increase in wind suction load capacity, a 112% increase in pressure load capacity (self-weight and snow), and 53% more capacity for combined loads compared with the standard UK Plain Tile roof hook, suiting sites with higher wind exposure or greater snow loading.
Thicker, Stronger Steel Construction
Manufactured from 8.0mm thick stainless and galvanised steel, noticeably thicker than the standard-load version, giving the hook greater resistance to bending and fatigue under sustained structural load.
Purpose-Built for UK Plain Tiles & Slate
Designed specifically for plain (flat) tiles and natural slate roof coverings common across the UK, giving a secure mechanical fixing point beneath the tile course.
Pre-Assembled for Faster Fitting
Supplied as a pre-assembled hook and baseplate, reducing on-site assembly time and the risk of incorrect component fitting.
Height-Adjustable Fixing
Includes a 20mm height adjustment slot, allowing the hook to be fine-tuned so the mounting rail sits at a consistent, level height across the tile course.
Compatible with the VarioSole+ Rail Range
Designed to work with Renusol VarioSole+ mounting rails, forming part of a complete, warrantied pitched-roof mounting system when used with genuine Renusol components throughout.

Frequently Asked Questions
What does 'HL' mean on this roof hook?
HL stands for High Load. This version is manufactured from thicker, stronger steel than the standard UK Plain Tiles/Slates roof hook, giving significantly higher wind suction, pressure, and combined load capacity for sites that require it.
What is the difference between this hook and the standard UK Plain Tiles/Slates hook?
The standard hook (MPN 420181) uses 6.0mm material thickness, while this High Load version (MPN 420184) uses 8.0mm material thickness, giving a 130% increase in suction load capacity, a 112% increase in pressure load capacity, and 53% more combined load capacity.
Are wood screws included with this roof hook?
No. This product is supplied pre-assembled but without wood screws. Suitable screws must be selected separately based on the rafter or batten timber being fixed into.
Which roof coverings is this hook suitable for?
This hook is designed for UK plain (flat) tiles and natural slate roofs. For pantile, S-shaped, or concrete interlocking tile roofs, the Renusol Roof Hook UK Pantile (MPN 420180) is the correct part instead.
Is this a genuine Renusol part compatible with the VarioSole+ system?
Yes. This is a genuine Renusol roof hook designed for use with the VarioSole+ (VS+) mounting rail range. Renusol mounting equipment should not be mixed with components from other manufacturers, as doing so can void the system warranty.
