ITEM: POST EXTENSION FOR SIGN ONE 80mm ( 3 3/4") POSTS

DESCRIPTION: The twin opposing receptors (No. 5 on technical sheet 4409DD) allows the user the ability to insert 6mm x 32mm ( 1/4" x 1 1/4") aluminium flat bar and therefore save costs, or preset post extension into concrete as a time saver.

CONSTRUCTION: We recommend 6mm x 32mm ( 1/4" x 1 1/4") aluminium flat bar which is a standard, however many sign contractors have had success with alternative sized flat bar or off cuts of flat sheets, cut to size.

SPECIFICATION:
STEP 1: A – Ascertain desired length of post extension and cut two ( 2 ) vertical flat bars
STEP 2: B – Cut cross bar to suit your post hole diameter
STEP 3: C – Weld or mechanically fix cross bar to a vertical flat bar (ie weld "B" to both "A’s"
STEP 4: D – Insert into bottom of sign post and weld or mechanically fix in position.
STEP 5: E – Cut infill P1484R to 25mm ( 1") long and insert into post opening (4409DD No.1) to finished concrete level, this allows butt joint of balance of infill.
STEP 6: F – Bore or dig suitable hole in ground, ensure safe excavation prior to ground breaking. Insert post and/or infill post into ground and concrete to suit.

ENGINEERS SPECIFICATIONS: Should be sought to ensure the size and method of the sign you have designed and to establish the suitability of its use prior to manufacture and installation.

APPLICATIONS: Flat bar off cut aluminium is less expensive than Sign One post P1485R, you can save costs by concreting a post extension into a concrete footing. Another time saving benefit is to pre-install post extension into your concrete foot prior to the full sign install. With this option care must be exercised to ensure posts are plumb and level. Can be used like a "cage of bolts".
