Universal stainless steel mast clamp kit for wide range of mast diameters. Made in the Czech Republic with original Mastrant design.
Very strong (thickness 4 mm ... 5/32", height 40 mm ... 1-1/2", screws M8 ... 5/16" length 60 or 100 mm ... 2-1/4" or 3-7/8") and durable (screws, nuts and washers are AISI 316, brackets AISI 304). Holds the mast in 6 or 8 points (lines).
The bracket is universal - can be used for both 3 or 4 directional configurations. Therefore 4 directional kits could be used as 3 directional too. In the bracket is a hole for security bolt (sold separately, code ACM1ST5 and ACM1ST6).
The holes Ø16 mm (5/8") for guys can adopt shackles / chain couplers / carabiners from size of 4 mm (5/32") and thimbles from size 3 mm (1/8") up to 10 mm (3/8").
Another option is using rubber pad between the clamp and the mast (sold separately in different thicknesses, weather and UV stabilized EPDM, code ACM1Rxx). It spreads the pressure on the larger surface of the mast, reduce slippage and moreover isolate the clamp from the mast.
Original design!
