- Extension tubing sections shall freely separate to allow for user modification to fit multiple applications unless otherwise specified.
- Tablock pins shall have a minimum tensile strength of 120,000 psi with a head marking. Alternately, connecting pins may be heat treated to a grade 8 spec. and coated olive drab green to distinguish from standard grade 2 type pins which are typically coated grey zinc w/ no markings.
- Stand bases shall be equipped with two cambuckle straps connected to base with a bolt plate fitting at base pivot bolt to allow for rapid initial stabilization unless otherwise specified.
