* IMPORTANT - these towers must be tied-in in addition to fitting stabilisers/outriggers.

OUTRIGGERS / STABILISERS - These are not included in tower kits.   Towers marked # need measures taken to provide acceptable stability & safety. These towers have a platform height exceeding 3 times their smallest base dimension so should either be tied-in securely to the building or have outriggers/stabilisers fitted.

CORRECT USE OF STABILISERS  -  stabilisers should be fitted to the corners of the tower when the platform height is over the maximum free-standing height of 11' 6" for 4'x4' & 6'x4' towers; or over 6ft for 4'x2' & 6'x2' towers. Outriggers increase the smallest base dimension and make towers stable at greater heights. When fitted correctly, they will make the tower safe to a maximum platform height of 22'6" (4' wide towers) or 17' 0" (2' wide towers). Taller towers must be tied-in at this height and again at maximum 6ft intervals.

Most domestic users only fit two outriggers (those away from the wall). The correct method of fitting outriggers is to use four (one at each tower corner) with the inner outriggers parallel to the wall giving a "K" formation. Full details of outrigger use are included in the Safety Notes provided with your tower.

TYING-IN AS ALTERNATIVE TO USING STABILISERS  -  ties must be positioned at the maximum free-standing heights shown above and repeated at maximum 6ft intervals. Wall ties should be made with sturdy wall anchors which expand in the brickwork or by bracing a stout beam across the inside of a window aperture. DO NOT tie to downpipes or other insubstantial fittings.

4' x 4' towers need 5 boards ;
6' x 4' towers need 8 boards ;
4' x 2' towers need 5 boards but 29" long & stops 1¾" from end ;
6' x 2' towers need 8 boards but 29" long & stops 1¾" from end.
