Gafa (construcció)

Gafa de bastiment

Una gafa[1][2] en el món de la construcció, és una peça de metall formant un angle de 90° proveïda d'una punta punxeguda que es clava en el marc de la porta i una altra ampla i plana, que es cimenta dins la paret. S'utilitza per encastar quelcom a la paret, principalment per a fixar peces de fusta a l'obra (p.e.: bastiments).[3]
