(Lengths of 165 to 307 available up to 23mtrs, 337 up to 14mtrs and 138,

Advantages of the DLYR range
of extrusions
1) 14 Extrusions all of similar
shape
2) A full range of investment cast alloy goosenecks available with a full
range of investment cast gooseneck sub components available off the shelf
also
3) We have a range of forward and aft sleaves available, the largest forward
sleave fits internally inside the DL487, DL437, DL387, DL337 and externally
to the DL247. The next smaller one fits internally to the DL307 and externally
to the DL231. The next one down fits internally to the DL277 and externally
to the DL210 and the smallest of the 4 fits internally to the DL247 and
externally to the DL195. All the smaller sections are easily matched to
high strength heavy wall tubes. The aft sleave fits inside all of the
extrusions but needs to be trimmed down slightly to fit inside the DL307
to the smallest section. These sleaves are used for joining, stiffening
and doublers for gooseneck attachment.
4) We have all mast extrusions with the exact same track. Another unique
feature is the myriad of options available in stiffening all of the extrusions
both forward and aft as well as athwartships either internally or externally.
It perfectly suits the 15/16” Nylatron batten slide fittings and
well suited to Monohulls up to 45ft and Multihulls up to 40ft. A bolt
rope track is available for smaller boats if required and this same track
suits a 50mm reduced section for use as a trailer sailer mast. Six different
bonafide options are available as RBC tracks that can be supplied in 7.6mtr
lengths and considerable cheaper than the genuine tracks available with
slug kits. Aligning extrusions are also available for the joins.
5) Available off the shelf ex Brisbane in all sizes DL138, 152, 387, 437,
and 487 all Australian made. DL165 through to DL337 all available ex mill
in China in quantities of 2000kgs per profile. Pricing available on request
and subject to change.
