WARNING! You must mount to solid deck construction using specified fasteners in all
mounting holes and nuts, washers or backing plates to achieve correct maximum working
load to avoid a failure leading to an accident.
Use “lock-off” to temporarily secure sheet. Do not use in place of a clutch, jammer or line stopper.

Mounting Instructions—6093 Only
Mount H-42862 on underside of
block to support axle area.
DO NOT OVER-TIGHTEN BOLTS!
CORRECT
Tighten bolts wrist tight (10 ft-lb/14 N-m)
IMPORTANT! Tighten bolts only wrist tight (10 ft-lb/14 N-m) to remove play between block and deck. Do
not use a power driver. Over-tightening will permanently damage footblock and cause sheaves to bind.
DO NOT USE A POWER DRIVER.
INCORRECT
Block Loading vs Angle of Deflection
Block load is a combination of the load on the line passing through the block, plus a block-loading
factor, determined by the angle which the block turns the sheet. See loading example for a single
footblock below. IMPORTANT! When footblock is double-stacked upper block is rated at two-thirds
of listed maximum working and breaking load.

Maintenance
Harken equipment requires minimal maintenance, but some is required to give the best service and to comply with
Harken's limited warranty.
Keep equipment clean by frequent flushing with fresh water. Lubrication is not required.
In corrosive atmospheres, stainless parts may show discoloration around holes, rivets and screws. This is not serious
and may be removed with a fine abrasive.
IMPORTANT! Exposure to some teak cleaners and other caustic solutions can result in discoloration of part
and is not covered under the Harken warranty.
