Panel Clamp Specification
Base is 300mm diameter and weighs approximately 4kg offering stability indoors (out of the wind). A base cover drops over the recycled rubber-like dense plastic base to present a neat finished appearance. The base is 50mm (2") thick.
The pole is a push fit into the base. The pole is telescopic, the lower part being 25mm (1") diameter with a locking clamp similar to a parasol pole to achieve height adjustment from 1.2m (4ft) up to 1.8m (6ft).
The specially designed clamp bars can be fitted either way up depending on the application - either to 'pinch' with a scissor action to hold a panel in compression (as with an easel) - or inverted to lock onto the inside edges of a frame to hold it in tension. The clamp bars are 300mm wide.
The panel width can be 900mm subject to stability considerations. Suitable materials include foamcore board (Kappa board or FoamEx), foam PVC such as Forex or composte substrates such as Dibond. The minimum panel thickness will be whatever offers sufficient stiffness - typically 3mm. The clamp bars will accept up to 10mm thick.
How the clamp bars attach: The lower clamp bar fits onto the bottom part of the pole and is locked at the required height to suit the bottom of the display board. A small plastic thumb wheel is provided to lock in poition. The upper clamp attaches to the very top of the pole with a ball-headed screw. This can be tightened by hand and the ball also serves as a decorative finial.
- In standard use the top clamp bar faces downwards and the lower one faces upwards - to clamp a panel like in an easel.
- When the clamping rails are inverted both top and bottom members must be turned over. Now the top rail faces upwards and a suitable frame with a rim at the back can be hooked onto and supported by the top rail. The bottom rail now faces downwards to latch onto the bottom rim of the frame or blackboard, preventing it being lifted off.
- Final clamping is undertaken with the lever-action clamp on the pole itself. A small amount of pressure is applied to ensure the panel or frame is secure. The clamp then lowered to lock everything firmly in place.
