ABSTRACT:
The guide comprises a pair of elongated matching bars with nail or screw bores through the mating surfaces thereof. The two bars are normally maintained slightly apart to lift over the heads of nails by compression springs and include rotating cam clamps which can close the strips together against the spring pressure. One embodiment includes end clamps for engaging the opposing edges of a board and the edge of a further board to be nailed at right angles thereto so that the nail positions are correctly located. Lengthwise and width adjustments may be provided in the guide. Another embodiment permits the guide to be slipped under nail heads that have been started in order to support the nail as it is further engaged by the hammer or out from under nail heads having been both started and initially driven. The device may have guide drillings both perpendicular and at an inclined angle to the surface upon which it is engaged.
