zinc-plated steel • extendable

This is a 6-pack of brass 15mm extension posts 32EP15-6 which can be used to lengthen any post-&-screws from our range of brass, silver or black interscrews.

Extensions are made from zinc-plated steel, and are not coloured to match the interscrews. This is usually inconsequential, since the posts are typically concealed by the item being bound.


Extension length 15mm. Diameter 5mm. Thread M4.


Extensions are available in 7mm, then 10 to 60mm in 5mm increments.

We also carry a range of brass, silver and black interscrews in various lengths. Interscrews, also known as post-&-screw sets, are the 'top and bottom' pieces for the extensions.


Interscrew components at The Photo Album Shop

Variables such as length, depth, diameter, thread length and pitch mean that it is HIGHLY UNLIKELY that our interscrews or extensions will fit into existing sets from different manufacturers. Instead of trying to match existing sets, we recommend that you consider replacing your existing interscrews entirely. This way you will be able to add extensions or obtain replacements later if required.
