• Props are adjustable to various height requirements.
• Quickly and early erected by unskilled Labour.
• Props are easy to handle and can be used time and time again.
• Compact design for economical transportation and storage.
• No loose parts to be lost or mislaid.
Note: Props must be braced in both directions by tubes and fixed couplers at approximately 250 mm above \prop nut when extended beyond 3.6 M or in near measure with same strength and load carry capacity |
