The extension mast is an essential component for mounting lightning rods. It allows an Early Streamer Emission (ESE) lightning rod to be raised above the highest point of the building to be protected, without the need for complex guy-wiring.
Franklin France offers a complete range of lightning rod extension masts, in stainless steel or galvanised steel, compatible with Active 1D+, 2D and 4D lightning rods, for a lightning rod elevation of up to 6.5 metres.
Each extension mast is designed for simple assembly (by socket fitting, set screw or M20 threaded connection), ensuring quick installation and excellent mechanical resistance to wind.
Support sockets for caulking or welding AFD2200FS
These sockets are designed to accomodate lightning conductor staffs or elevation rods by simple fitting. Like the elevation rods, they feature a hammered out section adjusted to 25 cm.They can be used as sockets for caulking in concrete cubes or can be welded to the structural steelwork.
Fixing brackets
Fixing brackets presented below are designed for lightning conductors installation such as :
– 2 fixing brackets for lightning conductors installation only or equipped with an elevation rod,
– 3 fixing brackets for lightning conductors installation with 2 or 3 elevation rods.
Distance recommended between brackets : 40cm
Other models are available in our catalogue.
Franklin France offers 3 ranges of extension masts for raising lightning rods, suited to the model of ESE lightning rod to be installed :
Made of stainless steel, these extension masts allow our Early Streamer Emission (ESE) Active 1D+ lightning rod to be raised up to 6 m in height, without guy-wiring. The sections simply fit together by socket connection, and the upper end is fitted with a threaded stainless steel socket (M20 pitch) to directly receive the lightning rod, with no additional accessory required. Available in 3 heights: 2 m (AFC1242MR), 4 m (AFC1442MR kit : 2 masts) and 6 m (AFC1642MR kit : 3 masts).
Made of high-strength steel, hot-dip galvanised (inside and out), these telescopic masts provide lightning rod elevation of up to 6.5 m without guy-wiring. The sections are fixed together using stainless steel set screws, for quick and durable assembly. The upper mast, AFC1035MR, threaded at M20 pitch, directly receives Active 1D+ lightning rods. For compatibility with 2D/4D models, the AFB0001MG threaded connector allows for straightforward assembly. Three extension mast heights are available: 3.75 m, 5.5 m and 6.5 m, by combining references AFC1035MR, AFC2042MR, AFC3050MR and AFC3350MR.
These stainless steel extension masts are specifically designed to raise Early Streamer Emission (ESE) Active 2D/4D lightning rods, up to 6 m in height without guy-wiring. The 2 m mast AFC2242MR fits directly onto the Active 2D lightning rod thanks to its dedicated socket connection system. The AFC2442MR (4 m) and AFC2642MR (6 m) kits allow the total height of the lightning rod mounting to be adjusted according to site requirements.
“Offset” fixing brackets AFZ0414PD 220 mm
Fixing by stud gun, bolting, taping…
Multi-purpose fixing brackets AFZ2802FU
To be used when the wall does not allow deep caulking. Fixed by stud gun, pluf or taping. Used to fix 2F elevation rods. Locked in place by a clip.
Three-feet saddle AFD3200FS
Three-feet saddle are designed for fixing the lightning conductors and elevation rods in terrace or on the ground. Made of galvanized steel, it can be used for every lightning conductors and elevation rods with a diameter of Ø 50 cm. A telescopic one AFD3300FS is avalaible in our catalogue.
Saddle AFD1411EB
Fixing of Active 1D®, Active 2D®, Active 4D® lightning conductors and 2. 10 m Franklin rods only on towers and metal frameworks.
Taping AFD2011PS
Generally used to fix lightning conductors and their elevation rods to stacks, concrete masts, etc. Associated to taping AFD2012PS (see our catalogue).
Water deflecting cones AFD5001CE
Water deflecting cones are mainly used for vertical fixings of lightning conductors and their support masts on roofs. Two rubber models are suitable for different passage diameters. Their reinforced aluminium alloy base, forming a plate, can be deformed to match different structural shapes while remaining water-proof. Possibility of fixing by sealed rivets. Can be available in other dimension under the reference AFD5002CE (see our catalogue).
