512SS and 512ESS Flush
Bolts - Suitable for Aluminium Doors
Henderson RMD is one of the most
influential hardware suppliers of Folding Door hardware
with Weatherfold Coastal leading the way in innovation
and performance.
The market for Folding Doors appears
to be as strong as ever with more window manufacturers
entering this sector including many from the aluminium
side of the industry. Weatherfold Coastal is suitable
for both timber and aluminium but in the case of
aluminium Henderson RMD was unable, until now, to
offer the complete hardware package.
The new 512SS and 512ESS flush bolts
have been designed specifically for the aluminium
sector and completes the Weatherfold Coastal package.

Specification
The Henderson 512 is
the only cast 316 stainless steel flush
bolt on the market available in locking
and non locking form.
It utilises the keying
and design features from the 456 timber
door products to retain the style and
appearance of the Henderson flush bolt
range.
The product is available
in three lengths, 400mm 600mm and 900mm.
The various lengths of tie rods position
the operating knob at the above mentioned
distances from the edge of the door.
Fitting the product
is very simple. The new flush bolt is
fitted from the inside of the aluminium
section to minimise the amount the product
protrudes from the surface. The cap
supplied to guide and hold the tie rod
is designed around a commercial 45mm
door stile that can vary anything up
to 3mm wall thickness.

Finishes
The new 512SS and 512ESS are available
in Satin Stainless with other finishes to follow
as the product grows in popularity. It is worth
noting that unlike the common lever type that has
to be powder coated to provide protection to the
zinc die casting the Henderson 512 is made from
stainless steel that does not require powder coated
Applications
Folding Door systems
The offset tie rod and square tip
of the 512 is designed around the channel and track
position of Weatherfold Coastal. By rotating the
tie rod it is possible to position the square tip
to fit directly into the channel under the door
or align it adjacent to the top track. The benefit
of this design is one bolt does all, inward and
outward openings without the need for keepers.
Swing Doors
In addition to achieving its original
design brief that being to accommodate folding door
systems the 512 is well suited for the general market
and can successfully be used on Swing and French
doors. Each flush bolt kit is supplied with a nylon
keeper to dress and seal the hole required in the
top and bottom sections.
Adjustment
Unlike the lever type flush bolt
which is prone to working loose, the 512 has a square
tip that stops the tie rod from rotating once the
door stile cap is fitted. Adjustment of the tie
rod is simple and effective, set the tip flush with
the edge of the door when the shoot bolt is full
retracted. To secure the tie rod simply insert the
stile cap and gently tap in place. The cap is designed
with an interference fit.
