Size 7 cruiser blocks
All with plain or ball bearing sheaves
This range of high load cruiser blocks are of a rugged construction featuring high quality injection moulded side plates with all load carrying components from 316 grade stainless steel. Side plates are thru-bolted and rivetted for added strength and security.
This good looking and versatile range is designed for use on larger crusing and racing yachts. All are designed for ease of use with our Ball Bearing Mainsheet Traveller Systems.
BALL BEARING BLOCKS:
With our unique super low friction Ball Race System featuring Acetal sheaves with Delrin ball bearings running on a large diameter centre boss. This allows us to fit more load bearing balls which ensure extremely low friction performance even under high loads.
PLAIN BEARING BLOCKS:
Have a precision moulded Acetal Sheave running on a large diameter centre bearing ensuring free running under extremely high loading.
FIXED EYE:
Has a plain attachment eye.
REVERSE SHACKLE:
Removable shackle can be set in line or at 90 degrees to the sheave.
SWIVEL:
Solid stainless steel swivel eye through a solid trunion assembly through bolted to the block is capable of operation under the highest loads. A forged stainless steel screw pin shackle is also fitted.
VARILOC MULTI HEAD:
Allows swivel to be locked at 30 degree positions in relation to sheave. Inverting the lock converts to swivel mode. Supplied with screw pin shackle.
SNAP SHACKLE:
Has a cast stainless steel swivelling snap shackle. Ideal for use as quick release downhauls or vang tackles.
STANDUP BLOCKS:
Have a flexible plastic spring for anti tumble action. Precision turned solid aluminium base. Base Dia: 67mm. Fastening Dia: 6mm.
CAMCLEAT BLOCKS:
Now fitted with our all new Kevlar 'K'Cam as standard. Stainless steel cam arms are all fully adjustable by moving the locking clevis pin to achieve the correct sheeting angle. This range of blocks used in conjunction with relevant fiddle blocks are particularly useful for use as mainsheet tackles, vang tackles or powerful downhauls on cruising and racing yachts and catamarans.

Where break and safe working loads are stated, it assumes that all sheaves are evenly loaded as in a purchase tackle. Uneven loading or loading of one sheave in a double or triple block will severely affect strength quoted.
If unsure please seek further advice.
Maximum rolling load on ball bearing blocks is the maximum free running load before ball bearings will distort. |
